Question

a zoo adds new animals. 20 are monkeys, 34 are zebras, 12 are elephants, and 4 are lions. find the probability that a new animal is not a monkey. p(not a monkey) = ? round your answer to the nearest hundredth.

Explanation:

Step1: Calculate total number of animals

$20 + 34+12 + 4=70$

Step2: Calculate number of non - monkey animals

$34 + 12+4 = 50$

Step3: Calculate probability

$P(\text{Not a Monkey})=\frac{50}{70}\approx0.71$

Answer:

$0.71$
