Back

Front

What does it mean for an outcome to have a frequency closest to its expected frequency?

Back

It means that the actual occurrence of that outcome is similar to what was predicted based on probability.

Front

How do you calculate the probability of an event?

Back

Probability is calculated as the number of favorable outcomes divided by the total number of possible outcomes.

What is a random number simulation?

Back

A random number simulation uses random numbers to model real-world situations and predict outcomes.

Front

What is the significance of equal-sized sections in a spinner?

Back

Equal-sized sections ensure that each outcome has an equal chance of occurring.

Front

How do you determine the expected frequency of an outcome?

Back

Expected frequency is determined by multiplying the total number of trials by the probability of the outcome.
