just need some help with number 5
Suppose that the time at which a businessperson leaves for lunch
(in hours after noon) is a continuous random variable X with
probability density function f(x) = c(1-x)2 for 0 < x < 1,
where c is the appropriate constant, and f(x) = 0 otherwise.
1.Determine the value of c for this to be a legitimate pdf.
2.Sketch this pdf. (Hand-drawn is fine.)
3.Determine the probability that this businessperson leaves for
lunch before 12:15. Also shade the region corresponding to this
probability in your pdf sketch.
4.Determine the probability that this businessperson leaves for
lunch at exactly 12:15.
5.Suppose that you notice that this businessperson has not yet left
for lunch by 12:30. Determine the (conditional) probability that
he/she will leave before 12:45, given that he/she has not left by
12:30.
