Final answer:

The probability of having all boys is 1/8.

Step-by-step explanation:

The probability of having all boys can be calculated using the concept of independent events.

Assuming that the probability of having a boy or a girl is equal (which is true in most cases), the probability of having a boy for each child is 1/2.

Since having a boy for each child is an independent event, we can simply multiply the probabilities together to find the probability of having all boys.

P(Boy) * P(Boy) * P(Boy) = (1/2) * (1/2) * (1/2) = 1/8
