Question
Suppose two players A and B are trying to throw a basketball through a loop. The probability
that player A will succeed on any given throw is p, and he throws until he has succeed r times. See screenshot for full question.
Explanation / Answer
a)
Player A: Ya = Xa + r
E( Ya ) = E( Xa ) + r --> E( Ya ) = ( r/p - r ) + r = r/p
Player B: Yb = Xb + mr
E( Yb ) = E( Xb ) + mr --> E( Yb ) = ( mr/mp - mr ) + mr = r/p
Therefore expected number of throws is the same.
b) b) Variance of Player B is smaller
