Ive been studying like mad so Im getting more comfortable with stuff, but this one problem is making me batty.
A newspaper advertises 5 different movies, 2 plays, and 3 baseball games for the weekend. If a couple selects 3 activities, find the probability that one of each will be selected.
They dont want to know all the different combinations that can be had (which I am now good at) they want the probability of each but then what, multiply that together?
5/30 * 2/30 *3/30 no that doesnt work. what do I do? what is the formula for this. Im looking thru the book and cant find one explanation. BAH!
