Front

Define simple probability.

Back

Simple probability is the likelihood of a single event occurring.

Front

Define compound probability.

Back

Compound probability is the likelihood of two or more events occurring together.

Front

What is the formula for calculating the probability of event A?

Back

P(A) = Number of favorable outcomes / Total number of outcomes.

Front

How do you calculate the probability of two independent events occurring?

Back

Multiply the probabilities of each event: P(A and B) = P(A) * P(B).

What is the probability of rolling a number less than 3 on a standard number cube?

Back

1/3 (since the numbers 1 and 2 are less than 3).
