Sir there is change in the question. Previously it was only B in S2 and now it's P(B) and because of that there is a change in the answer.

We take concepts from text books and standard universities. This concept is taken from Rosen text book.
I am saying that these question make us  to think for sure .
no its not same, earlier the question had B in S2 and now it's P(B) and because of this answer which shiuld have been A is C
i got -0.33 instead of 1 because of this.
