Anna has 15 red shirts,12 blue shirts and 14 white shirts. What is the probability that Mario randomly selects a red shirt or a white shirt?

Mutually exclusive or not mutually exclusive???
pls help​

Answer:

mutually exclusive

total number of shirts =31

P (r) = 15/31

P(w) =14/31

P( r or w) = 15/31 + 14/31

P (r or w) = 29/31
