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
