Experimental Probability

Front

What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials conducted.

Front

How do you calculate experimental probability?

Back

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

Front

If a spinner is spun 200 times and lands on a number 50 times, what is the experimental probability of landing on that number?

Back

1/4 (50/200 = 1/4)

Front

What is the experimental probability of rolling a 5 if a die is rolled 12 times and a 5 appears 4 times?

Back

1/3 (4/12 = 1/3)

Front

If a spinner is spun 30 times and lands on blue 12 times, what is the experimental probability of landing on a color that is not blue?

Back

3/5 (18/30 = 3/5)

Front

What is the experimental probability of rolling a 1 or 6 if a die is rolled 14 times and those numbers appear 6 times?

Back

3/7 (6/14 = 3/7)

Front

If a die is rolled 12 times and a 4 appears 2 times, what is the experimental probability of rolling a 4?

Back

1/6 (2/12 = 1/6)

Front

What is the total number of outcomes when rolling a standard die?

Back

6 (The outcomes are 1, 2, 3, 4, 5, 6)

Front

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

Back

It means the event is likely to occur based on the experimental results.

Front

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

Back

It means the event is unlikely to occur based on the experimental results.
