### CFA Practice Question

The probability that the unemployment rate will increase in January is 0.35. What is the probability that the unemployment rate will not increase in January?

A. 0.30
B. 0.35
C. 0.65

The answer is 0.65 because the sum of the probabilities of any set of mutually exclusive and exhaustive events is 1. The probability that the unemployment rate will not increase in January is 1 - the probability that it will increase in January, or 1 - 0.35 = 0.65.
