Probability Calculations using Venn Diagram

[@aryanamaranan8890]

out of all youtube videos like this, this one is really understandable.

[@servatile]

i agree

[@salma7006]

Thankyou so much. I don't feel stupid anymore.

Thank you for your help sir!

How would you do this question if you weren’t given the middle section?

[@0atmeall]

then that isnt a venn diagram

[@eka2213]

assuming you mean if the overlap of both sets (circles) is 0: the events (participation in classes) would then be mutually exclusive and all questions containing "AND" would result in 0 probability

[@maazaslam7455]

thanks now I can feel good about my exam

[@charlievannakorn6086]

Why did he minus 1 on q.3

[@joshemman]

It is called the complement rule. If the probability that it is going to rain is 0.4, then the probability that it is not going to rain will be 1 - 0.4 =0.6.

[@debako2852]

Hello
Please in the question 3, how does 1-30 give 20?

[@joshemman]

1 - 30/50 = 1 - 0.6 = 0.4

[@Dustinthewind108]

What is the probability that a randomly selected student took sociology given that they didn't take philosophy? Or Pr(S|~P)

[@joshemman]

P(S|~P) = P(S & ~P)/P(~P) = 11/20

[@krishnakhanchandani5784]

Very help full video

[@nimaabdullahi3125]

How to answer if they ask: What is the probability that a student chosen at random from this class?

[@joshemman]

'What is the probability that a student chosen at random from this class,' then the question is not finished. There should be additional information about specifics somewhere.

[@BriCurlyFries]

What is I was given how many students take neither but I wasn’t given how many take both? How would I go about to find how many take both?

[@joshemman]

What else were you given?

[@Alxroeve]

What if they haven't given us the number of students that is doing both the subjects?

[@joshemman]

Can you state what you are given?

[@Alxroeve]

Oh no I'm just asking what to do

[@adina_nyx]

why didnt the teacher just say this?

[@ArthurShirinka]

Thank you sir

[@francisignacio5192]

U da man

[@mariamismail2764]

thx i love u

[@Valxxtine]

REAL

[@rikiya6907]

I should've seen this sooner

[@altheaoc]

im confused on the number 3 one ToT

[@joshemman]

At 2:01, Philosophy total = 18 + 12 = 30.
P(Philosophy) = 30/50
P(no Philosophy) = 1 - 30/50

[@rhaizanaomhiesilvan4102]

Thank youu

[@imane9567]

THANKYOUUUUUUUUUUUUUUUUUUUUUUU
