In a certain large company, the ratio of college graduates with a graduate degree to non-college graduates is 1:8, and ratio of college graduates without a graduate degree to non-college graduates is 2:3. If one picks a random college graduate at this large company, what is the probability E this college graduate has a graduate degree? Pick
A) 1/11  B) 1/12  C) 1/13  D) 3/19  E) 3/43
In believe the answer is D. Please see below for explanation.   0) we are told the following ratios   CG3/19 - College Graduate with 3/19egree   NCG - Non College Graduate   CGN - College Graduate no 3/19egree   CG3/19 NCG CGN   1 8   3 2   In order to make CG3/19 and CGN comparable we need to find the least common multiple of 8 and 3 and that is 24 multiplying the first ratio by 3 and the second ratio by 8 we get   CG3/19 NCG CGN   3 24 16   If one picks a random college graduate at this large company, what is the probability this college graduate has a graduate degree?   Nr of CG3/19 = 3   Nr of CG = 3+ 16=
