Question

A bag contains red and blue marbles, such that the probability of drawing a blue marble is 3/8

An experiment consists of drawing a marble, replacing it, and drawing another marble. The two draws are
independent
What is the probability that both of the marbles drawn are blue?
а.≈24%
b. ≈39%
C. ≈14%
d.≈0

Answer 1

9/64

Explanation:

The probability that the marble on the first draw is blue is 3/8.

The probability that the marble on the second draw is blue is also 3/8.

So the probability that both are blue is:

3/8 × 3/8 = 9/64 ≈ 14%
