There are 34 men and 32 women at a party. Of these, 13 men and 19 women are married. If 2 people are chosen at random, find the probability that
a) both will be men
b) 1 will be a married woman and the other an unmarried man
c) both will be married

Can someone pls help me. I've tried drawing a tree diagram but don't know how to. Can someone pls draw a tree diagram and if not can you pls answer part b. Cheers!

Here you go
MM stands for married man, UM stands for unmarried man etc

Also keep in mind you don't neccessarily have to draw the whole tree, with practice you can just draw the part you're gonna use
