Suppose 5 men out

Answer :

Let us assume U1, U2 and A be the events as follows:

U1 = choosing men

U2 = choosing women

A = choosing orator

From the problems it is clear that men and women are equal in number. So, probability of choosing a men and women will be same.

From the problem:

P(A|U1) = P(Choosing orator from men) =

P(A|U2) = P(Choosing orator from women) =

Now we find

P(U1|A) = P(The chosen orator is men)

Using Baye’s theorem:

The required probability is .
