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 or experiments conducted.

Front

How do you convert a fraction to a percent?

Back

To convert a fraction to a percent, divide the numerator by the denominator and then multiply the result by 100.

Front

What is the probability of an event expressed as a fraction?

Back

The probability of an event is expressed as a fraction of the number of favorable outcomes over the total number of possible outcomes.

Front

How do you convert a percentage to a decimal?

Back

To convert a percentage to a decimal, divide the percentage by 100.

Front

What is the formula for calculating the probability of picking one of multiple events?

Back

The probability of picking one of multiple events is calculated by adding the probabilities of each individual event.

Front

If the probability of an event A is 1/3 and the probability of event B is 3/8, how do you find P(A or B)?

Back

P(A or B) = P(A) + P(B) - P(A and B). If A and B are mutually exclusive, then P(A or B) = P(A) + P(B).

Front

What is the experimental probability of rolling a specific number on a number cube?

Back

The experimental probability of rolling a specific number on a number cube is calculated by dividing the number of times that number is rolled by the total number of rolls.

Front

What does it mean if an event has a probability of 0?

Back

If an event has a probability of 0, it means that the event is impossible and will not occur.

Front

What does it mean if an event has a probability of 1?

Back

If an event has a probability of 1, it means that the event is certain to occur.

Front

How do you express 176% as a decimal?

Back

To express 176% as a decimal, divide 176 by 100, which equals 1.76.
