Let y = number of languages in which a person is fluent. According to Statistics Canada, for residents of Canada y has probability distribution P(0) = 0.02, P(1) =

0.81, and P(2) = 0.17, with negligible probability for higher values of y.

(a) Is y a discrete, or a continuous, variable?Why?

(b) Construct a table showing the probability distribution of y.

(c) Find the probability that a Canadian is not multilingual.

(d) Find the mean of this probability distribution.
