Question

Player A will shut out (win by a score of 21-0) player B in a game of racquetball with probability
21
P =
1+p
2
Р
1-p+p²,
where p denotes the probability A will win any specific rally (independent of the server). (See
[Keller, J], p. 267.) Determine, to within 10-3, the minimal value of p that will ensure that A will shut
out B in at least half the matches they play.
