Ethan's dresser contains 4 pairs of shorts, 1 each in the colors red, black, blue, and grey. his dresser also contains 3 t-shirts, one each in the colors black, navy, and grey. ethan has to get dressed in the dark, so he grabs a pair of shorts and a t-shirt at random from his dresser. what is the probability that he selects a grey pair of shorts and a grey t-shirt?

Step-by-step explanation:

In basic probability theory, AND means MULTIPLICATION and OR means ADDITION.

We want to find probability of grey pair of shorts AND grey T-Shirt. So we need to multiply the individual probabilities.

P(grey shorts) =  (total 4 colors and 1 grey)

P(grey tshirt) =  (total 3 colors and 1 grey)

P(grey shorts AND grey tshirt) =

3x^3-x^2+6x-9
