Question

a bag contains 42 red, 45 green, 20 yellow, and 32 purple candy. you pick one candy at random. find the probability that it is not yellow. p(not yellow) = \frac{?}{} simplify your answer completely.

Explanation:

Step1: Calculate total number of candies

Total candies = \(42 + 45+20 + 32=139\)

Step2: Calculate number of non - yellow candies

Non - yellow candies = \(42+45 + 32=119\)

Step3: Calculate probability

\(P(\text{not yellow})=\frac{\text{Number of non - yellow candies}}{\text{Total number of candies}}=\frac{119}{139}\)

Answer:

\(\frac{119}{139}\)
