Given that a large consumer goods company ran a television advertisement for one of its soap products.
B = individual purchased the product S = individual recalls seeing the advertisement B∩S = individual purchased the product and recalls seeing the advertisement
The probabilities assigned were P(B)=.20,P(S)=.40, and P(B∩S)=.12
a) P(B/S) = 
Yes we can continue the advt since P(B/A) >P(B)
b)
It is preferable to continue advt as chances of purchase after seeing advt is more than purchase without seeing advt.
c) P(B/S) =
The II advt has the bigger effect since conditional prob is more here.
