Question 1075715
Passing the exam at the first attempt, the probability is 0.75.  Assuming all who fail the first time (.25) try again, we get .6 x 0.25=.15. So, 0.75+0.15, or .90 of the people who try eventually succeed--leaving 0.1, or 10% of all learners fail to obtain a license. &#9786;&#9786;&#9786;&#9786;
