Question

A bag contains 42 red, 45

green,
20
yellow, and 32 purple candies. You
pick one candy at random. Find the
probability that it is yellow or not
green.

Answer 1

31

Explanation:

First of,

or, in probability is subtraction and not means you shouldn't use green (therefore leaving you with yellow and red)

Red = 42

Yellow = 20

P(Yellow or Not Green) =
`(R+Y)/(2)`

⁘
`(42+20)/(2)` =
`(62)/(2)`

Hence, 31
