Experimental Probability

Front

What is experimental probability?

Back

Experimental probability is the probability of an event occurring based on the results of an experiment or trial, calculated as the number of successful outcomes divided by the total number of trials.

Front

How do you calculate experimental probability?

Back

Experimental probability = (Number of successful outcomes) / (Total number of trials).

If a jelly bean is selected 44 times and 12 of them are red, what is the experimental probability of selecting a red jelly bean?

Back

The experimental probability of selecting a red jelly bean is 12/44, which simplifies to 3/11.

Front

What is the experimental probability of Jon making a free throw if he made 15 out of 35 attempts?

Back

The experimental probability is 15/35, which simplifies to 3/7.

Front

How do you convert experimental probability to a percentage?

Back

To convert experimental probability to a percentage, multiply the probability by 100.

Front

If Sarah hit the ball 3 times out of 8, what is her experimental probability of hitting the ball next as a percent?

Back

Her experimental probability is (3/8) * 100 = 37.5%.

Front

What is the experimental probability of a spinner landing on green or red if it has 5 sections of green and 5 sections of red?

Back

The experimental probability is (5 + 5) / 10 = 10/10 = 1/2.

Front

If Kate spun a spinner 75 times and landed on '3' thirty times, what is the experimental probability as a percentage?

Back

The experimental probability is (30/75) * 100 = 40%.

Front

What does it mean if an experimental probability is close to 1?

Back

If an experimental probability is close to 1, it means the event is very likely to occur based on the experimental results.

Front

What does it mean if an experimental probability is close to 0?

Back

If an experimental probability is close to 0, it means the event is very unlikely to occur based on the experimental results.
