2.)
AND vs. OR

Mrs. Loughry, the local Algebra teacher, has finally lost it. The principal found her yesterday playing "Nail the Turtle" from the top of the gym building roof.

There she was on the roof, throwing giant foam dice at the members of Dr. Miller's gym class. Onlookers reported that she screamed with joy every time a "turtle" was nailed. The gamblers in the crowd were figuring probabilities.

a.) What is the probability that she throws a number which is a multiple of three OR an even number?

b.) What is the probability that she throws a number which is a multiple of three AND and even number?
