Probability Distribution Chart

Does the following table represent a probability distribution?

• Yes, because each value of F(X) is between 0 and 1, and the sum of all values of F(X) is 1.

• No, because each value of F(X) is between 0 and 1.

• No, because the sum of all values of F(X) is 1.

• Yes, because all values of F(X) are the same.

It is a list, a table, a graph, or a formula of probabilities associated with each of its possible values.

Which probability value would satisfy the given probability distribution?

• 0.16

• 0.17

• 0.18

• 0.19

What is the mean of the probability distribution?

• 0.43`

• 1.66

• 1.26

• 1.64

• Yes, because all of the probabilities are between 0 and 1 inclusive and the sum of all the probabilities is 1.
• No, all probabilities are not be between 0 and 1 inclusive
• No, the sum of all the probabilities is not 1.
• Yes, because the distribution is symmetric
