<PRE><B>Question 1108971</B>
Do people take indoor swimming lessons in the middle of the hot summer? They sure do at the Webster Aquatic Center. During the month of July 2009 alone, 179 people participated in various forms of lessons.

Swim Categories	Daytime	Evenings Totals
Preschool       27 	33         60
Levels	        76	38        114
Adult and diving 4	6          10
Total	       107	77        184
-----------------------------------------
Suppose one swimmer was selected at random from the July participants.
(d) Find P(preschool) = 60/184
(e) Find P(daytime) = 107/184
(f) Find P(not levels) = (60+10)/184
(g) Find P(preschool or evening) = (60+77-33)/184
(h) Find P(preschool and daytime) = 27/184
(i) Find P(daytime | levels) = P(day AND levels)/P(levels) = 76/114
(j) Find P(adult and diving | evening) = 6/77
