Can a vector only be "equal" to another one if it is parallel to it?
There's no other way?

Q- 24 students in a class asked whether they like football or basket ball.
iv) a student who likes football is selected at random. what is the probability that this student likes basketball?
i know it's a simple qs, but please answer since my answer was different from my teacher's and since i don't know if it's from a past paper i can't use a mark scheme to check :|

u sure that question is complete? cz i dnt think theres any way of solving it with the info given...

well, if thats the question..

its not 14/24..

its 12/19

because..if the player likes basketball AND football he belongs to the group of 12..

however they say he likes football..first..so the larger group is 19

therefore, 12/19 .

Oops, I wrote the solution to the question before the one he asked. Sorry.
