You are asked to match three songs with the performers who made those songs famous. If you guess, the probability distribution for the number of correct matches is:

Probability 0.448 0.316 0.023 0.213

Number correct 0 1 2 3

What is the probability you will get:

a. Exactly one correct? (Round the final answer to 3 decimal places.)

b. At least one correct? (Round the final answer to 3 decimal places.)

c. Exactly two correct? (Round the final answer to 3 decimal places.)

d. Compute the mean, variance, and standard deviation of this distribution. (Round the final answers to 3 decimal places.)

Mean µ =

Variance σ2 =

Standard deviation σ =
