Consider the numbers 0, 10, 20, 30, and 40. multiply each by 4 and compare the result to 60 to determine into which of the following intervals the answer to the question "what number can you multiply by 4 and then add 8 to the product to get 60? " should fall.

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. the appropriate probability distribution for the random variable
