Question

There are 6 green, 4 pink, and 6 brown marbles in a hat. You pick 4 marbles from the hat. Marbles are returned after they have been drawn. Find the probability that the first marble is brown, the second marble is not brown, the third marble is pink, and the fourth marble is not brown. Give your answer as a decimal to the nearest thousandth.

Answer 1

0.037

Explanation:

Since the marbles are returned the total possibilites are always the same and the events are independent

Total marbles = 16

6/16 x 10/16 x 4/16 x 10/16 = 0.037
