In an organization number of women are µ times that of men. If n things are to be distributed among them then the probability that the number of things received by men are odd is 
Evaluate μ .
Text Solution
Verified by ExpertsCHECK THE SOLUTION.
μ = 3
Sol. Let p and q denote probability of things going to man and woman respectively.
Therefore p = 
Probability of men receiving r things is given by
P r = n C r . q n–r .p r .
So required probability is given by P 1 + P 3 + P 5 + ………
= 
= 
By comparison, we have 
⇒ 2 μ − 2 = μ + 1. Thus μ = 3
