Probability Review

Front

What is the complement of rolling a 4 on a number cube with sides numbered 1 to 6?

Back

The complement is rolling a 1, 2, 3, 5, or 6.

Front

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

Back

The probability is \( \frac{5}{6} \).

Front

If a coin is flipped three times, what is the probability of getting tails once and heads twice?

Back

The probability is \( \frac{3}{8} \).

Front

What is a tree diagram and how can it help in calculating probabilities?

Back

A tree diagram visually represents all possible outcomes of an event, making it easier to calculate probabilities.

Front

If you toss a coin 10 times and get tails each time, what is the probability of getting heads on the next toss?

Back

The probability is \( \frac{1}{2} \).

Front

What is the total number of outcomes when choosing from 3 types of bread and 5 types of sandwiches?

Back

The total number of outcomes is 15.

Front

Define probability in the context of a number cube roll.

Back

Probability is the measure of the likelihood that an event will occur, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

What does it mean for events to be independent in probability?

Back

Independent events are those whose outcomes do not affect each other.

Front

How do you calculate the probability of an event?

Back

Probability = \( \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} \)

Front

What is the probability of getting at least one head when flipping a coin three times?

Back

The probability is 7/8.
