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 w this college graduate has a graduate degree?  Select:
A) 1 / 11 B) 1 / 12 C) 1 / 13 D) 3 / 19 E) 3 / 43

divide(divide(divide(1, 8), divide(2, 3)), add(divide(divide(1, 8), divide(2, 3)), 1))
"in believe the answer is d . please see below for explanation . 0 ) we are told the following ratios cgd - college graduate with degree ncg - non college graduate cgn - college graduate no degree cgd ncg cgn 1 8 3 2 in order to make cgd 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 cgd 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 cgd = 3 nr of cg = 3 + 16 = 19 probability w of cgd / ( cg ) - > 3 / 19 answer d"
