Question 585015
m men and n women are seated at random in a row on m + n chairs.
What is the probability that all the men sit next to each other?

Procedure: Try this with small numbers.
Ex: 3men and 2 women : ways to succeed 3

Number of ways to succeed with m men and n women: n+1
P(all men sit next to each other) = (n+1)/(m+n)
