A box of 9 gloves contains two left handed gloves and seven right handed gloves.
a: If two gloves are randomly selected from the box, without replacement, what is the probability that both gloves will be right handed?
b: If two gloves are randomly selected from the box without replacement, what is the probability that there will be one right handed glove and one left handed glove?
c: If three gloves are selected with replacement, what is the probability that all three will be left-handed?
d: If you were sampling with replacement, what would be the answers to "a" and "b"?
