There's a basket containing 10 apples - 7 red and 3 green. What's the probability that upon drawing 3 apples, we get 2 red and 1 green?
I am sorry it'd take me a while to get the OA (I encountered this question in one of the GMATPrep tests
I believe - but would have to look back to figure the source) but I'd appreciate if someone would post the entire methodology to solve this problem.
I guess the answer would differ if the apples are drawn 3 in one go, or drawn one after another, without replacement. Can someone provide the solutions to both approaches?
