Out of 2560 families with 5 children each, the probability number of families all of whose children are girls is

Out of 10,000 families with 4 children each , the probability number of families all of whose children are daughters is

Out of 10,000 families with 4 children each , the probability number of families all of whose children are daughters is

Out of 800 families with 4 children each, the expected number of families having atleast one boy is

Out of 10000 families with 4 children each, find the frequencies of distribution of number of male children.

Assume that each born child is equally likely to be a boy or a girl. If two families have two children each, then the conditional probability that all children are girls given that at least two are girls , is

Assume that each born child is equally likely to be a boy or a girl. If two families have two children each, then the conditional probability that all children are girls given that at least two are girls , is

Assume that each born child is equally likely to be a boy or a girl. If two families have two children each, then the conditional probability that all children are girls given that at least two are girls , is

In a family, with two children, the probability of both children are girls is:

Assumes that each born child is equally likely to be a boy or a girl. If two families have two children each, if conditional probability that all children are girls given that at least two are girls is k, then 1/k=
