Answer with explanation:
→If a Family has five children, then Total likely outcome can be represented as:
Five Male =1
Five Female =1
4 Male +1 Female =4
4 Female +1 Male =4
3 Male +2 Female =10
3 Female +2 Male =10
Total Possible Outcome
=1+1+4+4+10+10
or
=2×2×2×2×2
=32
,i.e either a children can be a male or female.
→If all the five childrens are male , then in the family number of children fewer than 5 male children =32-1=31
→Probability of an Event
[tex]=\frac{\text{Total favorable Outcome}}{\text{Total Possible Outcome}}[/tex]
→→Probability of selecting a family with fewer than 5 male children
[tex]=\frac{31}{32}[/tex]
