Mrs. Jones is expecting a baby. The probability that it will be a boy is 1/2 and probability that the baby will have blue eyes is 1/4. What is the probability that she will have a blue-eyed boy?

  • A 1/8
  • B 1/4
  • C 3/8
  • D 1/2
  • E 3/4

The correct answer is A. 1/8

The probability of two independent events both happening is the product of their probabilities. 

So, the probability that Mrs. Jones will have a blue-eyed boy is the product of the probability that the baby is a boy and the probability that the baby has blue eyes.

Therefore, the probability is \( \frac{1}{2} \times \frac{1}{4} = \frac{1}{8} \).
