How do you calculate the expected value in a probability model?

Back

The expected value is calculated by multiplying each possible outcome by its probability and summing all these products.

What is the probability of an event?

Back

The probability of an event is a measure of the likelihood that the event will occur, ranging from 0 (impossible) to 1 (certain).

If a spinner has 6 equal sections, what is the probability of landing on any one section?

Back

The probability is 1/6, since there is one favorable outcome and six possible outcomes.

What does it mean for outcomes to be equally likely?

Back

Outcomes are equally likely if each outcome has the same chance of occurring.

How can you represent a probability model using a spinner?

Back

A spinner can represent a probability model by dividing it into sections that correspond to different outcomes, with the size of each section reflecting the probability of that outcome.

What is the complement of an event?

Back

The complement of an event is the set of all outcomes in the sample space that are not included in the event.

If the probability of event A is 0.2, what is the probability of not A?

Back

The probability of not A is 1 - 0.2 = 0.8.

What is a sample space in probability?

Back

A sample space is the set of all possible outcomes of a random experiment.

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

Back

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