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.

How do you find the probability of independent events?

Back

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

If a number cube is rolled twice, what is the probability of getting a 6 on the first roll and a number less than 5 on the second roll?

Back

1/9.

What is the probability of rolling an odd number on a standard die?

Back

The probability of rolling an odd number (1, 3, or 5) on a standard die is 3/6 or 1/2.

How many outcomes are there when rolling a die twice?

Back

There are 36 possible outcomes when rolling a die twice (6 outcomes for the first roll multiplied by 6 outcomes for the second roll).

What is the formula for calculating compound probability of two events A and B?

Back

P(A and B) = P(A) * P(B) if A and B are independent.
