The random variable x is the number of occurrences of an event over an interval of 10 minutes. It can be assumed 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 10 minutes is 5.3. The random variable x satisfies which of the following probability distributions?

A circuit is shown in the figure. C = 2.4×10-5 F. The AC source has a root-mean-square voltage Vrms = 100 V. When the AC source frequency is 60 Hz, the room-mean-square current in the circuit has its maximum value of 5 A. If the frequency of the AC source is changed to 90 Hz, what is the root-mean-square current in the circuit (unit in amperes, A)?
