Question 1183702
1. P(correct address) = P(correct address AND driver 1) + P(correct address AND driver 2) + P(correct address AND driver 3) = 0.285 + 0.196 + 0.45 = {{{highlight(0.931)}}}


***{{{highlight(Note)}}}:  Compare the final answer with that of tutor ikleyn, whose final answer is 0.391, which is a mis-arrangment of digits of the correct final answer.  
(Rather funny)



2.  P(driver 3| correct address) = P(correct address AND driver 3)/P(correct address) = 0.45/0.931 = {{{highlight(0.48335)}}}  (5 d.p.)


3.  P(driver 1| wrong address) = P(wrong address AND driver 1)/P(wrong address) = 0.015/0.069 = {{{highlight(0.21739)}}}  (5 d.p.)
