Answer #1
Speed Violation(S) No Speed Violation(G)
Cell Phone Users(C ) 25 75 100
Not Cell Phone Users(N) 25 25 50
50 100 150

Please note that I have taken C = Cell phone user and N = Not cell phone user as not defined in question

a)

?(?) = 100/150 = 2/3 = 0.67

(?) ?(?) = 50/150 = 1/3 = 0.33

(?) ?(?) =

= 100/150 = 2/3 = 0.67

(?) ?(? ??? ?) =

25/150 = 1/6 = 0.17

(?) ?(? ??? ?) =

25/150 = 1/6 = 0.17

(?) ?(? ??? ?) = 0

(?) ?(? ?? ?) = 125/150 = 5/6 = 0.83

(?) ?(? ?? ?) = 125/150 = 5/6 = 0.83

Please revert in case of any doubt.
