Explanation:

Odds are defined as the ratio of the probability of an event occurring to the probability of it not occurring. Probability measures the chance of an event happening (ranging from 0 to 1). Variation refers to differences in data values. Expectation is the average value of a random variable. Since the question asks for the measure of an event occurring against it not occurring, odds fit this definition.
