Best ResponseYou've already chosen the best response.1@rissyroo118: actually, the previous answer is incorrect (no offense intended!) ok, so there were originally 5 yellow apples and 12 total apples (3+5+4) = 12, correct? one red apple was taken away, so that leaves us with 5 yellow apples and 11 total apples probability of getting a yellow apple = #of yellow apples/# of total apples

Best ResponseYou've already chosen the best response.1nope, please try again: there were 12 apples at the beginning. Mary took away 1 apple, so how many apples were left?

Best ResponseYou've already chosen the best response.0wait so we divide the fractions or do we multiply them? I think we multiply them.

Best ResponseYou've already chosen the best response.1@Kash_TheSmartGuy : nope, no multiplication here. the question is NOT asking "what is the probability of getting a yellow apple on both tries", it's only asking for the probability of picking a yellow apple after the first red apple is taken away
