At a certain amateur bands rock show the ratio of freaks to nerds to geeks is 1:2:3. If these are the only types of people in the crowd, and each person in the crowd has the same chance of yelling rock on!, what are the chances that the next person who yellsrock on!will be a nerds?  Select:
A) 1
B) 1/2
C) 1/4
D) 1/3
E) 1/6
Another approach is to assign some nice values for the number of freaks, nerds and geeks.   Given: the ratio of freaks to nerds to geeks is 1:2:3   So, let's say there is: 1 freak, 2 nerds and 3 geeks for a TOTAL of 6 people.   P(next person who yells rock on!is a nerds) = (# of nerds in the crowd)/(TOTAL # of people in the crowd)   =2/6   = 1/3   Answer:   1/3
