There are 5 men and 3 women in a room. Given probability for men with beard is 1/10.

a) find the probability that there are three men with beard and two with no beard.
(Do i need to count three men with beard X two men with not beard? or only count for three men with beard?)

b)if two people are selected randomly from the people in the room, what is the probabiliy that both of them are men with beard?

Any idea?
