Question

Leslie is a biologist. She is going to randomly select one animal from her lab to study. There are 555 salamanders, 333 crayfish, and 121212 minnows in her lab.

Answer 1

Answer:

$0.25$

Step-by-step explanation:

Probability = Number of favorable outcomes / Number of people outcomes

There are $5$ favorable outcomes ( the $5$ salamanders).

There are $20$ possible outcomes ( the $5+3+12=20$ total animals).

P (salamander) $= \frac{5}{20} = 0.25$

Answer 2

Complete question is;

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:

P(salamanders) = 0.25

Step-by-step explanation:

We are given;

number of salamanders = 5

number of crayfish = 3

number of minnows = 12

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

Now, we want to find out the probability that the animal Leslie randomly selected is a Salamander.

Thus,

P(salamander) = number of salamanders/total number of animals

P(salamander) = 5/20

P(salamander) = ¼ = 0.25
