3. There are 12 temp emloyees in a company. 4 of them will be hired at permanent staff. If 5 of 12 of the temp staff are women, how many of the possible groups of 4 temp employees can consist of 3 women and 1 man?
The order does not matter so it is a Permutation question
for women, 3 selected out of 5 => 5P3
for men, 1 selected out of 7 => 7P1
total = 5P3 * 7P1 = 420
