Very lttle is known about the random variable U. It is known, however, that U is a continuous random variable such that the probability density function is zero for U< -2 and U 4, and is non-zero for -2 < U < 4 (a) Sketch a possible distribution function for U. Label any important details of your sketch (b) It is later found that the median of U is 2. On a fresh set of axes, sketch a possible distribution...

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
