Question

A pet store has two tanks of tropical fish. the first tank contains 9 blue fish and 8 yellow fish and the second tank contains 6 blue fish and 6 yellow fish. if keisha randomly purchases a fish from each tank, what is the probability that both fish will be blue?

Answer 1

Hey there!

In order to solve this problem, you'll need to determine the probabilities of picking a blue fish from both of the tanks, then multiply these together to get your final possibility. You can just multiply these together since they are independent events and don't affect each other. 

$\frac{9}{17} * \frac{6}{12} = \frac{9}{17} * \frac{1}{2} = \frac{9}{34}$

There will be a 9 in 34, or about a 26% chance, of choosing two blue fish. Hope this helped you out! :-)

Answer 2

If Keisha randomly purchases a fish from each tank, then the probability that both fish will be blue will be 25.47%.

What is probability?

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

A pet store has two tanks of tropical fish. the first tank contains 9 blue fish and 8 yellow fish and the second tank contains 6 blue fish and 6 yellow fish.

The total number of the fish in the first tank will be

Total = 9 + 8 = 17

The total number of the fish in the second tank will be

Total = 6 + 6 = 12

If Keisha randomly purchases a fish from each tank, then the probability that both fish will be blue will be

$\rm P = \dfrac{9}{17} \times \dfrac{6}{12}\\\\\\P = 0.2547\\\\\\P = 25.47\%$
