Compound Probability

Front

What is compound probability?

Back

Compound probability is the probability of two or more events happening at the same time. It can be calculated by multiplying the probabilities of the individual events if they are independent.

How do you calculate the probability of independent events?

Back

To calculate the probability of independent events, multiply the probabilities of each event occurring.

Front

What is an independent event?

Back

An independent event is an event whose outcome does not affect the outcome of another event.

Front

What is a dependent event?

Back

A dependent event is an event whose outcome is affected by the outcome of another event.

Front

If a coin is tossed and a die is rolled, what type of events are these?

Back

These are independent events.

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

Back

The probability is 1/6, since there are 6 faces on a cube.

Front

What is the probability of getting heads in a coin toss?

Back

The probability is 1/2, since there are 2 possible outcomes: heads or tails.

If you have 4 different toppings and 3 types of ice cream, how many combinations can you make?

Back

You can make 12 combinations (4 toppings x 3 types of ice cream).

Front

What is the formula for calculating compound probability of independent events?

Back

P(A and B) = P(A) * P(B), where P(A) and P(B) are the probabilities of events A and B.

What is the total number of outcomes when rolling a die and tossing a coin?

Back

There are 12 total outcomes (6 outcomes from the die x 2 outcomes from the coin).
