Experimental Probability

Front

What is experimental probability?

Back

Experimental probability is the likelihood of an event occurring based on the results of an experiment or trial, calculated as the number of times the event occurs 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).

Front

If the experimental probability of an event is 0.4, what does this mean?

Back

It means that in a large number of trials, the event is expected to occur 40% of the time.

Front

In an experiment, if 500 cars pass by and the experimental probability of an SUV is 0.4, how many SUVs can be expected?

Back

200 SUVs (0.4 * 500 = 200).

What is the most likely outcome when selecting from a set of crayons with varying colors?

Back

The color with the highest quantity is the most likely to be selected.

Front

If Brooke has 45 yellow, 12 green, 25 blue, and 7 red crayons, which color is most likely to be selected?

Back

Yellow, because it has the highest quantity (45 crayons).

What is the experimental probability of rolling a 1 if you roll the dice 5 times and get 1, 3, 3, 4, 4?

Back

1/5 (1 occurrence of 1 out of 5 rolls).

Front

If you roll a die 12 times and get the following results: 1, 2, 3, 4, 5, 6, 4, 5, 6, 4, 5, 6, what is the experimental probability of rolling a number greater than 4?

Back

1/2 (6 occurrences of numbers greater than 4 out of 12 rolls).

Front

What is the experimental probability of rolling a 4 if you rolled a die 12 times and got 2 fours?

Back

1/6 (2 occurrences of 4 out of 12 rolls).

Front

What does a probability of 1/6 indicate about an event?

Back

It indicates that the event is expected to occur 1 time out of 6 trials.
