Question 1031844
A set of 101 hypothetical CWU students were surveyed about whether they lived on or off campus and how much ice cream they ate per week. The results are shown below: 

Ice Cream......... On-campus Off-campus...Totals 
At most two scoops... 23........ 27.........50 
Three to five scoops. 21........ 16.........37 
More than five scoops. 5......... 9.........14 
Totals................49.........52.........101
 (a)   What is the probability that a randomly chosen student lives on campus?
-----49/101
-------------------      
 (b)   If a person eats at most two scoops of ice cream per week, what is the probability that they live on campus?
-----23/50
---------------------      
 (c)   If a person lives on campus, what is the probability that they eat at most two scoops of ice cream per week?
-----23/49 
--------------------     
 (d)   Are the events "lives on campus" and "eats at most two scoops of ice cream per week" independent? Your answer should be "Y" or "N".
Question??: P(lives on camp)|eats >= 2 ) = P(lives on campus)*P(eats>=2)
(23/50) = (49/101)(50/101)
Answer:: No
Therefore the events are not independent?
