The total number of hours, measured in units of 100 hours, that a family runs a vacuum cleaner over a period of one year
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 125 hours; (b) between 60 and 75 hours. X. 0<x< 1 f(x) = 2-X, 1<x<2 0, elsewhere (a) The probability the family runs the vacuum cleaner less than 125 hours is (Type an integer or decimal rounded to three decimal places as needed.)
