probability and statistics

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 purple

Answer 1

Probability = number of events/the number of possible outcomes

In this problem this translates to:

(red+green+purple+yellow candies)/(total candies)

(28)/(42+45+20+32) = 28/139 = 0.23
