Independent Events Probability Practice

Front

What is the probability of rolling an even number on a number cube?

Back

The probability of rolling an even number (2, 4, or 6) on a number cube is 3/6 or 1/2.

Front

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

Back

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

Front

What is the formula for finding the probability of independent events?

Back

The probability of independent events occurring together is the product of their individual probabilities.

Front

If the probability of event A is 1/4 and event B is 1/2, what is the probability of both events occurring?

Back

The probability of both events A and B occurring is (1/4) * (1/2) = 1/8.

Front

What is the probability of rolling a 4 on a number cube?

Back

The probability of rolling a 4 on a number cube is 1/6.

Front

What is the probability of rolling an even number on a number cube and then rolling a 4?

Back

The probability is (1/2) * (1/6) = 1/12.

Front

What is the probability of tossing a coin and getting heads?

Back

The probability of getting heads when tossing a coin is 1/2.

Front

What is the probability of getting tails four times in a row when tossing a coin?

Back

The probability is (1/2)^4 = 1/16.

Front

What is the probability of landing on red in a spinner with 3 equal sections (red, blue, green)?

Back

The probability of landing on red is 1/3.

Front

What is the probability of landing on red first and green second when spinning a spinner twice?

Back

If the spinner has 3 equal sections, the probability is (1/3) * (1/3) = 1/9.
