An urn has 52 balls, 48 black, 4 white. 5 balls are drawn without replacement. What is the probability of getting 3 white balls and 2 black ball?

Solution

4a.

There are 52C5 ways to choose any 5 balls.

There are 4C3 ways to choose 3 white, and 48C2 ways to choose 2 black.

Thus,

P = [(4C3)(48C2)]/(52C5) = 0.001736079 [ANSWER]
