Morgan Stanley is hosting an investment conference in sunny Phoenix and the investors attending the conference are offered to either play tennis or golf. 90% of the attendees who know how to play tennis also know how to play golf, whereas, 18% of the attendees do not know how to play either sport and will stay in their hotel rooms and do their homework to prepare for their breakout meetings. If 30% of the conference attendees do not how to play tennis, then how many attendees know how to play golf?

1)38.0%
2)46.5%
3)66.0%

Ok, I'll give it a try.

Question 1: 4) 75%
Question 2: D) 66.8%

**texaslefty** · 12-31-2003

if 30% don't know tennis then 70% do know tennis. 90% of the players that know tennis know golf (.7x.9)= 63%. the 18% that don't know anything must be included in the 30% that don't know tennis which yields another 12% that do know golf adding up to 4)75% that know golf.

even if this is wrong i can still eliminate 1,2,5.

**texaslefty** · 12-31-2003

since 30% do belong 70% don't belong. golfers are comprised of 90% average, 8% good, 2% exceptional. of these golfers 40% of exceptional do not belong and 30% of good don't belong.

.7=(.4)(.02)+(.3)(.08)+x

d)66.8%
