On a particularly busy section of the Garden State Parkway in New Jersey, police use radar guns to detect speeders. Assume the time that elapses between successive speeders is exponentially distributed with a mean of 22 minutes.

What is the probability of a waiting time less than 12 minutes between successive speeders? (Round your answer to 4 decimal places.)

What is the probability of a waiting time in excess of 21 minutes between successive speeders? (Round your answer to 4 decimal places.)
