Answer 2

Answer:

In a family of 3 children, to find the probability of having at least 1 boy, let us find the probability of no boy.

The sample space for different cases contains 2

3

=8 points. [ As there are 3 children and the child may be boy or a girl] among which there is only one case when there are all girls that means no boy.

So probability of no boy is

8

1

.

So the probability of at least one boy is 1−

8

=

8
