Let no. of books be x

No. of history books equal x into 1/3 I.e.x/3

No. Of English books equal x into 1/3 I.e. x/6

Rest books = no. Of science books

=total books -(history books+English books)

=×-(×/3 +×/6)

=x-(3x/6)

=x-x/2

=x/2 books are of science of total books I.e. x

No of science book is 1/2 of total books

**Kiran**, Monday, October 14, 2013 at 8:36pmAs per the probability rule

Total of all probability is 1

So,

P(History)+P( English)+P( Science) = 1

1/3 + 1/6 + P( Science) = 1

P( Science) = 1- (1/3 + 1/6) = 1 - 1/2

P( Science) = 1/2
