Find the experimental probability that exactly 3 of 4

puppies will be female.
The problem has been simulated by tossing 4 coins (one to
represent each puppy). Let "heads" represent male and
"tails" represent female. A sample of 20 coin tosses is
shown.

Answer:

4 / 20 (1 / 5)

20%

Explanation:

The experimental probability is what actually happens in an experiment (as opposed to an authentic probability calculated from genetics).

In this experiment, there are 3 outcomes with :

3 tails and 1 head

(tails represent female, head represent male)

So, 4 / 20 of the time, this coin flip was what we call a "success" (meaning that it matches the guidelines that we want)

4 / 20 = 20% of the time

So, the probability of a group of 4 puppies being 3 females and 1 male is :

4 / 20 (1 / 5)

20%
