Question

These marbles are randomly put in a bag and two of them are randomly drawn.

2 yellow, 3 pink 5 blue
What is the probability of drawing two pink marbles if the first one is not placed back into before the second draw
Give your answer as a ratio, reduce to simplest terms
Hint: multiply the probability of the first event to the second event two get your answer

Answer 1

P(pink) = 3/10
P(2nd pink w/o replacement) = 2/9
both multiply them together 3/10 * 2/9 = 15/90 = 1/6
