Hillary and her friends could flip a coin twice to fairly decide which activity they will do. If the coin lands on heads one time and tails one time, they will go bowling. If it doesn't, they will go to a movie.
What is probability?
Probability is the ratio that shows the likelihood of an event occurring out of all the other possible events.
Hillary and her friends need to use a fair method to determine which activity to do. For this, the probability should be 1/2. We should observe the given options and find which is the fairer method.
- In the case of option A, the probability of that event occurring is 1/4.
- In the case of option B, the probability of that event occurring is 1/2.
- In the case of option C, the probability of that event occurring is 1/8.
- In the case of option D, the probability of that event occurring is 3/8.
- We can see that Option B is the only event having a probability of 1/2.
Therefore, Hillary and her friends could flip a coin twice to fairly decide which activity they will do. If the coin lands on heads one time and tails one time, they will go bowling. If it doesn't, they will go to a movie. The correct answer is Option B.
