Probability of Simple Events

Front

What is the probability of an event?

Back

The probability of an event is a measure of the likelihood that the event will occur, expressed as a number between 0 and 1.

Front

How do you calculate the probability of a simple event?

Back

The probability of a simple event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Front

What is the formula for calculating the probability of NOT choosing a specific outcome?

Back

The probability of NOT choosing a specific outcome is calculated as 1 minus the probability of choosing that outcome.

If a letter tile is chosen at random from a set of 9 letters, what is the probability of choosing a specific letter?

Back

The probability of choosing a specific letter is 1/9, assuming each letter is equally likely to be chosen.

Front

What is the probability of choosing one of several specific outcomes from a set?

Back

The probability of choosing one of several specific outcomes is the sum of the probabilities of each individual outcome.

Front

How do you express probability as a fraction?

Back

Probability can be expressed as a fraction by writing the number of favorable outcomes as the numerator and the total number of possible outcomes as the denominator.

What is the probability of choosing an orange mint if there are 5 mints in total and 1 is orange?

Back

The probability of choosing an orange mint is 1/5.

Front

What does it mean if the probability of an event is 0?

Back

If the probability of an event is 0, it means that the event cannot occur.

Front

What does it mean if the probability of an event is 1?

Back

If the probability of an event is 1, it means that the event is certain to occur.

Front

How do you find the probability of multiple independent events occurring?

Back

The probability of multiple independent events occurring is found by multiplying the probabilities of each individual event.
