Question

An animal sanctuary is home to 57 mammals, 60 birds, 15 reptiles, and 12 amphibians. If one of the animals is selected at random, find the probability that the animal is a reptile.

Options:
A. 0.12
B. 0.15
C. 0.17
D. 0.20

Answer 1

To find the probability of selecting a reptile from the animal sanctuary, we divide the number of reptiles by the total number of animals, which results in 0.1042. Option B, 0.15, is the closest to our calculated probability and is therefore the correct answer.

Step-by-step explanation:

The question asks us to find the probability of selecting a reptile at random from an animal sanctuary that houses 57 mammals, 60 birds, 15 reptiles, and 12 amphibians. To calculate this probability, we add the total number of animals in the sanctuary and then divide the number of reptiles by this total.

First, let's find the total number of animals:
57 mammals + 60 birds + 15 reptiles + 12 amphibians = 144 animals in total.

Now, we calculate the probability that the animal is a reptile:

Probability = Number of Reptiles / Total Number of Animals
Probability = 15 reptiles / 144 total animals

When we calculate this, we get:

Probability = 0.1042

However, this number is not one of the options provided. Since probabilities are often rounded, we check the options to see which is closest to our answer.

Option B, 0.15, is the closest to our calculated probability and is therefore the best choice.
