then what is the expected number of games played in the series
If two teams A and B play a best-of-five series, and if team A has a 1/4 chance of winning any game (and team B has 3/4 chance of winning any game), then what is the expected number of games played in the series. (Note that in a best-of-five series, the teams play games until one team has won three games.)

equivalence relation
let P(A) be the powerset of set A.and let R be the relation on P(A) such that S1 R S2 when S1 = S2.then the relation is: 1.reflexive 2.transitive and reflexive 3.reflexive and symmetric 4.equivlence relation here i am not getting one thing,relation ... that is s1 != s2 and hence there will not be any element in the reltion. I am confused with the language of the question.

Hi. I am new to Gate preparation. It would be very helpful if someone could clarify: Are Section 1.6 and 1.7 (Introduction to Proofs and Proof Methods and Strategy) from Kenneth Rosen (6th Edition) part of the Gate Syllabus? I didn't see them mentioned in the syllabus, hence asking. Thanks.
