n ice cream seller takes 20 gallons of ice cream in her truck each day. Let X stand for the number of gallons that she sells. The probability is 0.1 when X = 20. If she doesn’t sell all 20 gallons, the distribution of X follows a continuous distribution with pdf f(x) = cx if 0 < x < 20, where c is a constant that makes P(X < 20) = 0.9. What is the value of c?
