Asked by Michelle
The signers of the declaration of Independence came from the 13 colonies as shown:
Massachusetts: 5
New Hampshire: 3
Virginia: 7
Maryland: 4
New Jersey: 5
Pennsylvania: 9
Rhode Island: 2
New York: 4
Georgia: 3
North Carolina: 3
South Carolina: 4
Connecticut: 4
Delaware: 3
Suppose that 4 are chosen at random. Find the probability that 2 come from Pennsylvania and 2 come from Virginia
I'm not sure where to start, but I do know we've been using Permutations and Combinations.

If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
9/56 * (9-1)/(56-1) * 7/(56-2) * (7-1)/56-3) = ?
Which formula would fit best?
