What is compound probability?

Back

Compound probability refers to the probability of two or more events happening at the same time. It can be calculated using the multiplication rule for independent events.

How do you calculate the probability of independent events?

Back

To calculate the probability of independent events, multiply the probability of the first event by the probability of the second event. P(A and B) = P(A) * P(B).

What is the total number of outcomes when spinning a spinner twice?

Back

The total number of outcomes is the product of the number of outcomes for each spin. If there are 4 sections, then 4 * 4 = 16 outcomes.

What is a sample space in probability?

Back

A sample space is the set of all possible outcomes of a probability experiment.

How do you find the probability of an event?

Back

The probability of an event is found by dividing the number of favorable outcomes by the total number of possible outcomes. P(Event) = Number of favorable outcomes / Total outcomes.

What is the formula for calculating the probability of two dependent events?

Back

For dependent events, the formula is P(A and B) = P(A) * P(B given A).
