How do you find the probability of two independent events occurring together?

Back

Multiply the probabilities of each event. This is known as the 'and' rule in probability.

Front

What does it mean to cross multiply in a proportion?

Back

Cross multiplying involves multiplying the numerator of one fraction by the denominator of the other fraction to find equivalent ratios.

Front

What is the vertical line test?

Back

Independent events do not affect each other's outcomes, while dependent events do.

Front

What is a proportion?

Back

A proportion is an equation that states that two ratios are equal.

Front

How do you solve a linear equation?
