Amagician is performing for an audience of 32 men and 20 women. he selects a volunteer from the audience, has the volunteer stand behind a curtain, and then selects another volunteer. what is the probability that both volunteers are men? (shown as a percent)

32+20=52 so there are 52 people in all. 
32/52  people are men.
we now have to subtract 1 from this fraction like so 32-1/52-1 since the magician took away 1 man from the audience (therefore reducing the amount of men as well as the audience as a whole) resulting in 31/51
we multiply 32/52 with 31/51 to get 248/663. simply turn this fraction into a percent by multiplying the quotient by 100 and rounding it to the nearest tenth to get 37.4%
