Question:1
(a) Assume that the time taken in a call service center is an exponential random variable X with parameter λ=1/10. If someone makes a call just before you do, find the probability that the waiting time will be:
i) Less than five (5) minutes.
ii ) Between 5 and 10 minutes.
(b) The probability density function (PDF) of a continuous random variable is given in Fig.

Calculate the Continuous Distribution Function (CDF) and do its plot.
