Aki is a participant on a trivia-based game show. He has an equal likelihood on any give trial of being asked a qeustion from one of six categories: Hollywood, strange places,Number Fun, Who?, Having a Ball and Write On! Aki feels that he has an 50/50 change of getting Having a Ball or Strange Places questions correct, but he thingks he has a 90% probability of getting any of the other questions right. If Aki has to get two of three questions correct, what are his odds of winning?
The answer is 43/50, my teacher can't solve it- - what'd hell, the question sounds easy, but it relates to something i haven't learned. like binomial probability and combinations, any body help? Thank you very much.
