In each choice, click the button beside the gamble that you would rather play.

Now, look at the first choice below. Would you rather play:

```        A: 50 tickets to win \$100
50 tickets to win \$0 (nothing)
OR
B: 50 tickets to win \$45
50 tickets to win \$35

Think of probability as the number of tickets in a bag containing 100 tickets,
divided by 100. Gamble A has 50 tickets that say \$100 and 50 that say \$0, so
the probability to win \$100 is .50 and the probability to get \$0 is .50. If
someone reaches in bag A, half the time they might win \$0 and half the time
\$100. But in this study, you only get to play a gamble once, so the prize will
be either \$0 or \$100. Gamble B's bag has 100 tickets also, but 50 of them say \$45,
and 50 of them say \$35. Bag B thus guarantees you win at least \$35, but
the most you can win is \$45. Some will prefer A and others will prefer B.
To mark your choice, click the button next to A or B. Notice that the dot
next to No. 1 will empty and fill in the button next to your choice.

For each choice below, click the button beside the gamble you would rather play.
After people have finished their choices, three people will be selected randomly
to play one gamble for real money. One trial will be selected randomly from the
20 trials, and if you were the lucky person, you will get to play the gamble
you chose on the trial selected. You might win as much as \$100. Any one of
the 20 choices might be the one you get to play, so choose carefully.
Winners will be notified by email. Offer void where prohibited by law.
