+474 A member of the junior varsity swim team will be elected as President. Each member is equally likely to be elected. The probability that a sophomore is elected is times the probability that a freshman is elected. Everyone on the junior varsity swim team is either a freshman or sophomore. What fraction of the swim team are sophomores?
+266 ...really?
First of all, at least try the problem before copy and pasting it onto this site
Second of all, you didn't even copy it RIGHT. I would expect you put a little more effort so that people can READ your problem, and answer it occordingly.
You can post it again and I will answer it. Post it with the corrections.
+45 I've seen this problum so i'm assuming that the ratio is 3:2, That means if everyone has an equal chance to be president, the ratio of sophomore swimmers to freshman swimmers is 3:2. So 3/(3+2) is 3/5 of the team are sophomores.
