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
Answer:
[tex]0.25[/tex]
Step-by-step explanation:
Probability = Number of favorable outcomes / Number of people outcomes
There are [tex]5[/tex] favorable outcomes ( the [tex]5[/tex] salamanders).
There are [tex]20[/tex] possible outcomes ( the [tex]5+3+12=20[/tex] total animals).
P (salamander) [tex]= \frac{5}{20} = 0.25[/tex]
