Answer:
0.75
Step-by-step explanation:
It is given that having a boy or girl as children are the two events which are equally likely.
i.e. Probability of having a boy or a girl is equal to or 0.5.
Let P(B) be the probability of having a boy and P(G) be the probability of having a girl child.
So, P(B) = P(G) = 0.5
<u>To find:</u> Probability that out of two children, atleast one boy is born.
Required probability = 1 - Probability that both the children are girls
Required probability :
So, the probabilty that atleast one boy is born out of two children is <em>0.75.</em>
