Probability Review

Front

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

Back

The probability is 1/3, as there are 2 favorable outcomes (5 and 6) out of 6 possible outcomes.

What are the possible outcomes when flipping a coin?

Back

The possible outcomes are Heads and Tails.

Front

What is a dependent event in probability?

Back

Dependent events are events where the outcome of one event affects the outcome of another.

Front

What is an independent event in probability?

Back

Independent events are events where the outcome of one event does not affect the outcome of another.

What is a probability distribution?

Back

A probability distribution is a function that describes the likelihood of obtaining the possible values that a random variable can take.

Front

What is the sum of probabilities in a probability distribution?

Back

The sum of all probabilities in a probability distribution must equal 1.

Front

What are the possible outcomes when picking a number between 1 and 5?

Back

The possible outcomes are 1, 2, 3, 4, and 5.

Front

What is the formula for calculating the probability of an event?

Back

The probability of an event is calculated as P(E) = Number of favorable outcomes / Total number of outcomes.

What does it mean if two events are mutually exclusive?

Back

Mutually exclusive events cannot occur at the same time.
