Sagot :

The probability of drawing a white marble followed by a yellow marble, without replacing the white marble is 0.091

How to determine the probability?

The distribution of the marbles is given as:

White = 3

Yellow = 4

Green = 5

Total = 12

The probability of selecting a white marble is:

P(White) = 3/12

Now, there are 11 marbles left.

The probability of selecting a yellow marble is:

P(Yellow) = 4/11

The required probability is:

P = 3/12 * 4/11

Evaluate

P = 0.091

Hence, the probability of drawing a white marble followed by a yellow marble, without replacing the white marble is 0.091
