Question

Simple probabilityLeslie is a biologist. She is going to randomly select one animal from her lab to study. There are 5 salamanders, 3 crayfish, and 12 minnows in her lab.If necessary, round your answer to 2 decimal places.

Answer 1

Answer:
`P(salamanders)\text{ = 0.25 }`

Step-by-step explanation:

Given:

number of salamanders = 5

number of crayfish = 3

number of minnows = 12

To find:

the probability of salamanders

To determine the P(salamanders), we will divide the number of salamanders by total animals

Total animals = 5 + 3 + 12

Total animals = 20

`\begin{gathered} P(salamanders)\text{ = }(5)/(20) \\ \\ P(salamanders)\text{ = }(1)/(4) \end{gathered}`

In decimal place:

`P(salamanders)\text{ = 0.25 \lparen2 dp\rparen}`
