Q1) Waiting time, in hours, between successive speeders spotted by radar unit is continuous random variable with cumulative distribution function

F(x) = 0,       x < 0,

       = 1 - e^(-8x)             x ≥ 0.

Determine probability of waiting less than 12 minutes between successive speeders

i) By using cumulative distribution function of X.

ii) By using probability density function of X.
