In the solution, the displayed formulas should be: $922.78 - $845.57 = $77.21. and $922.78 + 4·$77.21 = $1231.62. Apologies for typos in the formulas shown in this solution.

There is a typo in the solution, the third formula: Instead of: 1.0349103^1.5 in the denominator, it should be 1.03510988^1.5.

I might be late, but can someone explain why we needed to get the determinant?

Why didn't we solve it using multinomial ?

Why didn't we solve it by multinomial?

At time 12:49 approximately, the likelihood for life 2 is missing term mu_x ^12, corresponding to one observed death occurring from state 1. This term should be multiplied at the end of the terms stated for likelihood for life 2.

Professor! Thanks for the new video! Can you link a pdf version of the text on the video?? Thanks

I just drew a 2-way table and filled it in. So much easier for me.

I just started studying for MAS 1 but I referred to some Exam P thought (kinda rusty). Why wouldn’t a negative binomial distribution work?

Is this on the IFM syllabus? I saw it say it was an MFE question.

how do i know that both options put and call have long positions?

Do we assume the stock pays no dividend?

the answer is B here. 0.53 and not 0.54

I need this . Thanks

Why is the covariance not zero since the support is rectangular implying independence?

Tricky problem

this is super easy

When tricky problems, suddenly become intelligible...Many thanks Prof. Ostaszewski

Hi, I calcualted this question by using the method provided in Question 9 (Exam FM exercise for June 29, 2017), which is multiplying the weights by (1*2)/(1.03)^3, and (2*3)/(1.03)^2 respectively. But the results gives 5.5809 in half yrs and we converted by dividing the result by 4, which gives us 1.3952 yrs squared. Why this method is not appropriate for this question?

Should the numerator be the one mupltipied by (1+i), which in this case is e^(0,05). Since the question is asking for Macaluay duration. And -PV'(i)/PV(I) in the answer provided is Modified duration.

Are we assuming the interest charged on the notional amount is fixed for this question? Since if the interest rate charged is not fixed then the 25million should be multiplying 8% and 30million should be multiplying 6%.

Wow that so hard, you are so genius sir, salute

Thank you for an especially interesting problem, Prof. Ostaszewski. I have a question: If W is a non-decreasing function of X (and strictly increasing for X > 20), is it necessary to break the probability into two pieces? After all, the only X-value for which W = 115 is 150. Therefore, we might write: The event [W = 115] is equivalent to [40 + X/2 = 115], which is equivalent to [X = 150]. Hence, P(Y < 115) = P(W < 115 | X > 20) = P(X < 150 | X > 20), which proceeds directly to the end of your solution via memorylessness. Did I leave something out?

Could you please post more MAS 1 problems proffesor? I appreciate your work. Thanks for sharing.

How was the deduction made that this is a gamma distribution

how does the index decrease by 1 in step 4?

There are some typos in the solution, my apologies. The result of the first calculation should be 919.39, and the result of the last calculation should be 9.8456%, answer choice D. I posted a corrected solution at: rumble.com/vdnhnv-exam-fm-exercise-for-april-14-2017.html

you can do this in 1 step using the memoryless property of the exponential distribution. good video though for refreshing earlier concepts

Hi Professor, thank you for the video. I'm not quite sure where the third term comes in ('Interest paid at the end of year 5 on deposits....'). Are you summing up the four $100 interest payments received at T = 2 to 5 separately in the third term and calculating their accumulated interest separately in the second term (100.(Is).3/6%)? Just want to make sure if I'm following along correctly.

This guy's humor lol. Love it!

Really targets those fundamentals very nice question! Thanks!

Thanks profess-sir!

Hi professor thanks for these videos! Sorry if this comes across as silly, but i'm running through the 421 questions in the playlist, and i was wondering if they're all still relevant for FM? I decided to run from most recent to least so as to ensure they're most relevant after the 2017 syllabus changes but was wondering if that's something i should worry about.

very helpful :)

I enjoyed your video so much. I have been trying to find for a RUclips video similar to yours that informs everything in this RUclips vid. 🧑🏻‍⚕️ 🧑🏻‍⚕️Your vid for sure is like the vids from this educational med student Doctor Ethan! Dr's tips are totally insightful and he helped me a lot on finals. He is a helpful Doctor. Go see his RUclips out and give Doctor Ethan a like! ➡️ #DrEthanOnline

Very nice 😍💋 💝💖♥️❤️

I don't understand why the reserve is not writing in terms of the annuities, and only with the pay in expenses and premium of the next year

Found this resource thank you very much

Found this resource thank you very much

@6:30 - 'The purpose is to get rid of you' - I laughed hard at that LOL. Thank you for all these great videos and solutions!

My apologies for a typo, in the video, it says that the link to it is ​smartURL.it/KO-LTAM-Exercise129, but it actually is: @t

Thank you Sir, for adding these videos this make me in practice

This solution is actually more confusing than the SOA's solution.

The final result is wrong. The total price is 1640.26+943.40=2583.66. P.S. Thanks for the explanation. :)

sorry sir I think There's a typographical mistake. V^n = 0.5975029875 and not 0.59999253.

I havent studied finance in 10 years. This all looks familiar but lacks detail. Wish you put it in laymens terms. Needed you to show how your formulated the formula and how everything gets plugged in.

at z=1.27 p=.8980 and at z=1.28 p=.8997 doesn't that make the answer 89th percentile?

Thank you for this, want to be youtube friends?

At the beginning of the problem, it is mistakenly stated that this comes from the Written Answer section of the Spring 2020 LTAM exam. The problem, of course, comes from the multiple choice section. My apologies for this mistake.

Beautiful solution
