Help on my homework please!

A box contains 24 colored mugs 10 red, 8 yellow and 6 green.

a) a mug is selected at random. what is the probability that the mug chosen is either red or green? is this an independent even or a dependent event or mutually exclusive?

b) a mug is selected at random. what is the probability that the mug chosen is EITHER red or yellow?

c) a mug selected at random, what is the probability that the mug chosen is both red and yellow?

I am also confused with which equation to use when it comes to both or either?
