The total number of hours, measured in units of 100 hours, that a family runs a vacuum cleaner over a period of one year is a continuous random variable X that has the density function shown below. Find the probability that over a period of one year, a family runs their vacuum cleaner (a) less than 135 hours; (b) between 30 and 100 hours. X, 0<x< 1 f(x) = 2-X, 15x<2 0, elsewhere
