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(salamander)? if necessary, round your answer to 2 decimal places.

Answer

Explanation:

Step1: Calculate total number of animals

$5 + 3+12=20$

Step2: Calculate probability of selecting a salamander

$P(\text{salamander})=\frac{\text{Number of salamanders}}{\text{Total number of animals}}=\frac{5}{20} = 0.25$

Answer:

$0.25$
