Leslie 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. What is P{salamanders}.

Answer:

0.25 or 25%

Step-by-step explanation:

Since there are number of salamanders = 5

number of crayfish = 3

number of minnows = 12

total number of animals n = 5 + 3 + 12 = 20

She wants to randomly select an animal and check if it is Salamander or not.

$P(salamanders)=\frac{n(S)}{n}$

                = $\frac{5}{20}$

                =  $\frac{1}{4}$

                = 0.25 or 25%

Answer 2

Answer:

The answer is 0.25.
