2. On a roulette wheel, there are 38 slots numbers 1-36 along with 0 and 00. Half of the 36 slots are red and the
other half are black. O and 00 are green slots. Let's say that we walk up to a roulette wheel and place a $5 bet on
black. If the ball lands on a black slot we get our original bet back ($5) plus another $5 for winning. Of course, if the
ball lands on a red or green slot we lose our $5 bet.
What will be our expected gain and standard deviation if we play two games betting $5 each time on black?
