Hi  
NOte: correction on gender
	       female 	male	Tot
satisfied	80	55	135
not satisfied	120	45	165
     Tot	200	100	300
A viewer was randomly selected from those surveyed.
P(satisfied) = 135/300 = 9/20
(F 0r not satisfied) 
= P(f) + P(not satified) - P(unsatisfied female) = 200/300 + 165/300 - 120/300  = 245/300 = .8167 rounded
P(satisfied| male) = 55/100 = 11/20

Wish You the Best in your Studies.
