Q2 of 47 Page 1

In a family of 3 children, calculate the probability of having at least one boy.

Here, a child can be either a boy (B) or a girl (G).

Thus, the sample space is


S = {(B, B, B), (B, B, G), (B, G, G), (G, G, G)


⸫ S = 4


The event at least one boy can be represented by,


E = {(B, B, B), (B, B, G), (B, G, G)}


⸫ P (E) =
