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

Use a standard normal table to determine the probability. give your answer as a decimal to four decimal places. −1.5< < 1.5)

So can you show me how to do the work and what 5 miles equals how many yards
