Simple and Compound Probability

Front

What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

What is a simple probability?

Back

Simple probability refers to the probability of a single event occurring.

Front

What is a compound probability?

Back

Compound probability refers to the probability of two or more events occurring together.

Front

How do you calculate the probability of a single event?

Back

The probability of a single event is calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

What is the formula for calculating simple probability?

Back

The formula is: P(A) = \frac{Number\ of\ favorable\ outcomes}{Total\ number\ of\ outcomes}.

What is the probability of rolling a 3 on a standard die?

Back

The probability is P(3) = \frac{1}{6}.

Front

What is the probability of drawing a red card from a standard deck of cards?

Back

The probability is P(Red) = \frac{26}{52} = \frac{1}{2}.

Front

What is the difference between independent and dependent events?

Back

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

Front

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

Back

For independent events A and B, P(A and B) = P(A) * P(B).
