Driving test You are about to take the road test for yourdriver’s license. You hear that only 34% of candidatespass the test the first time, but the percentage rises to72% on subsequent retests.a) Create a plan for a simulation to estimate theaverage number of tests drivers take in order to geta license.b) Here are results of 100 trials of a simulation. Use theseresults to estimate the average number of tests driverstake in order to get a license.
