Answer:

12.5%

25%

50%

25%

12.5%

50%

Explanation:

In this case, each event has a probability of 1/2, because the coin only has two faces, dog or cat.

Therefore the probability will be the multiplication of the probability of each event.

What is the probability of getting three dogs?

(1/2) * (1/2) * (1/2) = 0.125 = 12.5%

What is the probability of getting 2 cats?

(1/2) * (1/2) = 0.25 = 25%

What is the probability of getting 1 dog?

(1/2) = 0.5 = 50%

What is the probability of getting 2 dogs?

(1/2) * (1/2) = 0.25 = 25%

What is the probability of getting 3 cats?
