Question

Park contain 4 blue, 2red and 3 black pens. If a pen is drawn at random from the pack, NOT replaced and the process repeated 2 more times, what is the probability of drawing 2 blue pens and 1 black pen

Answer 1

Step-by-step explanation:

You have 9 pens.

P(blue) = 4/9

P(black) = 3/9

P(2 blue + 1 black) = 4/9 * 4/9 * 3/9
