### Instructions for Decision Making

In this study, each gamble is an urn containing either two or three tickets. Each ticket is identical, except that they have different prize values printed on them. One ticket will be drawn blindly and randomly from your chosen gamble to determine your prize. Assume that each ticket is equally likely to be drawn. For example, in Choice W1 below, the first gamble has two tickets that win \$15 or \$20 and the second gamble has two tickets as well, which might win either \$5 or \$95. Which gamble would you rather play? Click the button to indicate your choice.
