The probability density function of X, the lifetime of a certain type of device (measured in months), is given by 0. f(x) = if æ < 12 if x > 12 Find the following: P(X > 23) = -0.895 The cumulative distribution function of X: if æ < 12 F(x) = 1-(12/x) if æ > 12 The probability that at least one out of 7 devices of this type will function for at least 40 months: 11/42
