Coloring Book or Crayon

[nycmathguy]

Ginger has a box of items. There are 24 coloring books and 36 crayons. What is the probability of selecting a coloring book or a crayon from the box?

The events are mutually exclusive. Yes?

Let x = coloring book

Let y = crayon

P( x or y) = P(x) + P(y)

P(x or y) = 24/60 + 36/60

Correct set up?
