Question

You are feeling kind of crazy, so you are going to have the owner of the pet store randomly pick a fish for your aquarium at home.

a. A tank at the pet store contains 9 spotted guppies, 14 red barbs, 10 red tetras, and 7 golden platys. What is the probability (expressed as a percent) of getting a red-colored fish from this tank?

b. In a different tank that contains only golden platys, the probability of getting a female fish is 30%. If there are 18 female fish in the tank, how many total fish are in the tank?

Answer 1

a. you will have a 70% chance of getting a red fish.

B. there are 60 fish in the tank total 

Answer 2

A. The probability of getting red-colored fish from the tank is 60%.

b. The total number of fish in the tank is 60.

The calculation is as follows:

a. The probability is

$= (14 + 10) \div (9 + 14 + 10 + 7)\\\\= 24 \div 40$

= 60%

b. The total no of fish in the tank is

$= 18 \div 0.30$

= 60

In this way,  both parts should be calculated.
