Probability of both being boys- 1/4

Answer:

1/4

Step-by-step explanation:

It would be 1/4 because for the first child, the probability of it being a boy is 1/2, and for the second one, it would have 1/2 as well. There are 4 ways the first two children could have been:

1. boy boy - it is 1/4 of the options.

2. boy girl

3. girl boy

4. girl girl

Another way to solve it is by multiplying 1/2 by 1/2.
