**Reiny**, Friday, February 15, 2013 at 10:27amI am not familiar with your notation of ⌊1000p⌋

but I would do it this way:

after a W prob(W) = 7/10 , prob(L) = 3/10

after a L, Prob(W) = 3/10, prob(L) = 7/10

To have a 4-game series in a best of 5 setup, the winning team could win in these ways

LWWW --- (1/2)(3/10)(7/10)(7/10) = 147/2000

WLWW --- (1/2)(3/10)(3/10)(7/10) = 63/2000

WWLW --- (1/2)(7/10)(3/10)(3/10) = 63/2000

Prob = (147+63+63)/2000 = 273/2000
