There are 6 married couples attending a party where two door prizes (the prizes are the same) are awarded to two different people. Solve to 3 decimal places.

What is the probability a married couple wins the prizes?
What is the probability one prize goes to a man and one to a woman?

If John's wife Mary wins a prize, what is the probability that John will also win a prize?

If Mary does not win a prize, then what is the probability that John will?

You got into college how? Grab your text book and read about permutations and combinations.

That exact problem is given as an example in the notes for Chapter 5, Section 3 in the online MA114 course. It is in either the third or fourth movie part.

it doesn't matter who the prizes go to, once one has been given out, everyone else still has the same odds of getting the last prize whether they're married to the first winner or not.
