Question

Brenda has 18 fish in an aquarium. The fish are the following colors: 5 orange, 7 blue, 2 black, and 4 green. Brenda’s trouble-making cat has grabbed a fish.

What is the probability the cat did NOT grab an orange fish?

1/3


3/4


13/18


13/5

Answer 1

The answer would be 13/18

Answer 2

It should be 13/18

Explanation:

Subtract the number of orange fish from the total number of fish. The number you get will them be divided by the total number of fish.

18- total number of fish

5-total number of orange fish.

18 - 5 = 13

13 divided by 18

13/18
