An exponential probability distribution

An experiment consists of measuring the speed of automobiles on a highway by the use of radar equipment. The random variable in this experiment is speed, measured in miles per hour. This random variable is a _____ random variable.

If P(A) = 0.61, P(B) = 0.48, and P(A ∪ B) = 0.82, find P(A ∩ B).

When dealing with the number of occurrences of an event over a specified interval of time or space, the appropriate probability distribution is a _____ distribution.

For a normal distribution, a positive value of z indicates that

The random variable x is the number of occurrences of an event over an interval of ten minutes. It can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. It is known that the mean number of occurrences in ten minutes is 5.3. Which of the following discrete probability distributions’ properties are satisfied by random variable x?
