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
