Question

Neha has 4 yellow t-shirts, 6 black t-shirts, and 2 blue t-shirts to choose from for her outfit today. She chooses a t-shirt randomly with each t-shirt equally likely to be chosen. Find the probability that a black or blue t-shirt is chosen for the outfit.

Answer 1

If Neha chooses a t-shirt randomly with each t-shirt equally likely to be chosen, then the probability that a black or blue t-shirt is chosen for the outfit is: $P(Black Or Blue) = \frac{6 + 2}{4+6+2} = 2/3$ or 0.667.
