Exercise 14

Using View #1 [ game cannot end in a tie ],
find the house edge when a craps player bets the don't pass line.

  Let B = the amount bet on the don't pass line
  Let p = P( win )   =   949 / 1925
 
  Let E = expectation   =   Bp + ( - B ) * ( 1 - p )   =   2Bp - B
  = B * ( 2p - 1 )
 
  H = | E / B |   =   | 2p - 1 |   =   | ( 1898 / 1925) - 1 |
  = | - 27 / 1925 |     1.403%
