A deck of 9 cards contains 2 red cards, 3 blue cards, and 4 green cards. 3 cards are randomly drawn with replacement from the deck. What is the probability that all three cards are the same color?  Choose one.
A) 11/81	B) 64/729	C) 5/7	D) 27/729	E) 2/5
Note that cards are drawn with replacement. So every time we draw from 9 cards and it's possible to draw 3 red cards, 3 blue cards or 3 green cards:   P=(2/9)3+(3/9)3+(4/9)3=11/81   11/81nswer: 11/81.
