Probability: "Or" and "And" Probabilities

This is the second video of a series from the Worldwide Center of Mathematics explaining the basics of probability. This video deals with calculating probabilities for the union and intersection of events. For more math videos, visit our channel or go to www.centerofmath.org.

He speaks as if someone kidnapped him and forced him to make a probability video.

Thank you! My unit test is tomorrow, so I was unsure about this. Thanks for clearing it up!

[@jakekeenan1304]

Agreed cuh

[@amrabdelhakim1585]

I got what I needed from the video so thank you. However, reading out examples, rather than writing them, may not prove to be the best path for these kinds of videos.

Thanks! My math final is tomorrow, so this video really helped me review.

Did u pass?

[@nataliewing4337]

@@aj-rm7kk Yes! :)

You made it more confusing than it is

[@huyanhle]

Can anyone help me how to solve this question please!
Madison has a choice of two entrees (soup or salad), three main courses (fish, chicken, or steak), and three desserts (ice-cream, lemon tart or cheese).
Suppose Madison has the choice to omit the entree and/or the dessert course altogether. Find the probability that:
(i) She chooses soup, fish and lemon tart (Answer = 1/36)
(ii) she chooses all three courses (Answer = 1/4)
(iii) she chooses only two courses (Answer = 1/2)
(iv) she has only the main course. (Answer = 1/4)

what if you dont have the given probabilty part too find the both probability

Thank and now I hv understand it

[@peymanzada8169]

Thanks.

[@stephanievojtek1816]

Thank youuu!

[@samanthakrueger-gundy2998]

Wrong. umm there are three different dice possibilities for getting a sum of 6 though. 3 +3, 5+1, or 1+5. You only accounted for one of the one plus five problems. But you can roll a 1 on the first dice and a 5 on the second OR a 5 on the first die and a 1 on the second.

[@stephanierossmoine2743]

This is the easiest class so far and I have a feeling it's gonna get really difficult soon
