Please give me detailed solution to this problem:

Suppose I pick a jelly bean at random from a box containing eight red and four blue ones. I record the color and put the jelly bean back in the box.

If I do this three times, what is the probability of getting a blue jelly bean each time? (Round your answer to three decimal places.)

Solution

Total number of beans=4+8=12

Number of blue beans=4

Probability of picking a blue bean=4/12=1/3

Probability of getting a blue bean three times in a row=1/3*1/3*1/3=1/27= 0.037
