The waiting time, in hours, between successive speeders spotted by a radar unit is a continuous random variable with a cumulative distribution function F(x)={ 0, x<0 1-e^-4 x, x ≥ 0. Find the probability of waiting fewer than 12 minutes between successive speeders (a) using the cumulative distribution function of X; (b) using the probability density function of X. | Numerade
