Question

A family has two children. Find the probability that both the children are girls given that at least one of them is a girl?.

Answer 1

A family that has two children, both are girls, given that at least one of them is a girl, has probability of 1/2 or 50%.

Probability is the likelihood of an event to occur. The value is from 0 to 1 or from 0% to 100%.

For an experiment having n number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.

Probability (Event) = Favorable Outcomes/Total Outcomes = x/n

Given that at least one of the two children is a girl, then we are sure that one must be a girl. The other child will either be a boy or a girl. The possible outcomes could have been:

(G, G) and (G, B)

Probability (Event) = Favorable Outcomes/Total Outcomes = x/n = 1/2 = 50%
