Simulation. Set money lower limit to 0, check that box and no others (play 'til you go broke).

Money: Start with \$100 - enough to make 20 losing bets.

Run Simulation - see how long it takes you to go broke, highest bet, ...

• See what happens as you vary some of the starting values:
• Give the house a 2% advantage by setting the ratio to 0.98.
• Allow yourself to play longer by starting with more money, or reducing the initial bet.
• Try to figure out what some of the other inputs mean.

• Housing opportunity index: www.nahb.org/generic.aspx?sectionID=135&genericContentID=533
The Housing Opportunity Index (HOI) for a given area is defined as the share of homes sold in that area that would have been affordable to a family earning the local median income based on standard mortgage underwriting criteria. Therefore, there are really two major components -- income and housing cost. For income, NAHB uses the annual median family income estimates for metropolitan areas published by the Department of Housing and Urban Development. NAHB assumes that a family can afford to spend 28 percent of its gross income on housing; this is a conventional assumption in the lending industry. That share of median income is then divided by twelve to arrive at a monthly figure.
