Hi,

Re TY

(54-35) = 19, Statistics only

(69-35) = 34, finance only

 19 + 34 =53,  Statistics only or finance only

100 - 19 - 35 - 34 = 12, those who take neither

100 students, 54 studied Statistics, 69 studied Finance and 35 studied both subjects



P(S OR F) = 

P(neither) = 

P(F but not S) =
