P(having unprotected more than 2 times)=P(X>2) =P(X=3)+P(X=4)=0.4+0.3 =0.7
P(number is fewer than 4 and more than 2) =P(X=3)=0.4
therefore P( fewer than 4 and more than 2 given more than 2 times)=P(X<4|X>2) =P(2<X<4)/P(X>2)=0.4/0.7=0.57
option C is correct

:13-19 Every home football game for the past eight years at Eastern State University has been sold out. The revenues from ticket sales are significant, but the sale of food, beverages, and souvenirs has contrib- uted greatly to the overall profitability of the football program. One particular souvenir is the football pro- gram for each game. The number of programs sold at each game is described by the following probabil- ity distribution:...
