document.write( "Question 1026012: A roulette wheel has 38 slots numbered 00, 0, 1, 2, ..., 35, 36. Eighteen of the slots numbered 1 through 36 are red and eighteen are black. The 00 and 0 slots are green. The ball is spun around the wheel until it falls into one of the slots. When a gambler bets $1 on a single number and wins, he gets $36 back (i.e. his net winnings are $35). Find the expected value of this game (in dollars). \n" ); document.write( "

There are 38 numbers available.
\n" ); document.write( "So the probability of winning is 1/38 and of losing is 37/38.
\n" ); document.write( "\"E=%281%2F38%29%2836%29-%2837%2F38%29%280%29-1\"
\n" ); document.write( "\"E=36%2F38-1\"
\n" ); document.write( "\"E=36%2F38-38%2F38\"
\n" ); document.write( "\"E=-2%2F38\"
\n" ); document.write( "\"E=-1%2F19\"
\n" ); document.write( "\"E=-0.05\"
\n" ); document.write( "So you expected values is a loss of a little more than a nickel.
