Answer:
1/8
Step-by-step explanation:
Let
- Event A: The first-born is a boy.
- Event B: The second-born is a boy.
- Event C: The third-born is a boy.
Considering one birth, the probability of having a boy is 0.5 or 1/2.
Each birth is independent of the previous one. The probability that independent events occur is equal to the product of the individual probabilities.
P (A and B and C) = P(A).P(B).P(C) = 1/2 . 1/2 . 1/2 = 1/8
