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 5.4. What is the appropriate probability distribution for the random variable? a)continuous
b)either discrete or continuous depending on how the interval is defined
c)binomial
d)discrete

Please answer the question thoroughly.
Exercise 4.10. A number is chosen uniformly from the interval [0, 1). The random variable X outputs -2 if the chosen number falls in the interval [0, 1/4). It outputs 1 if the chosen number falls in the interval [1/2,2/3). Otherwise, the random variable iply outputs the chosen number. Find the distribution function Fx associated to X, find its discrete and continuous parts, Fxd and Fxe, and draw their graphs.
