Question

(13 POINTS) (SHOW YOUR WORK) Jordan is a biologist. She is going to randomly select one animal from her lab to study. There are 55 salamanders, 33 crayfish, and 12 minnows in her lab. What is the probability that she does not select a salamander?

Answer 1

The probability that Jordan does not selects a salamander is
`(11)/(20)` or 0.55

Explanation:

First, we will have to add up all of the number of animals.

55 + 33 + 12 = 100

Now, we find the ratio of 55 and 100 to get the probability.

55 / 100 = 11 / 20

So, the probability that Jordan does not selects a salamander is
`(11)/(20)` or 0.55
