Question

A box contains 5 purple marbles, 3 green marbles, and 2 orange marbles. Two marbles will be drawn from the box, and the first one taken out will NOT be put back in. What is the probability of drawing a purple marble, then a green marble?

Answer 1

P(purple) = (# purple) / (total # marbles)

 

multiply that by:

 

P(2nd is green) = (# green) / (# marbles remaining)
