wheel with spaces marked 0 through 36 and a space marked 00 means that there are 38 possible events
\n" ); document.write( ":
\n" ); document.write( "a) 1/38 = 0.0263 = 2.6%
\n" ); document.write( ":
\n" ); document.write( "b) 37 to 1 against winning
\n" ); document.write( ":
\n" ); document.write( "c) If your number 7 wins, you have a net gain of $19. If your number 7 does not win, you lose the $1
\n" ); document.write( ":
\n" ); document.write( "expected value = 19(1/38) + (-1)(37/38) = -0.4736
