Now, look at the first choice, No. 1, below.   Would you rather play: 
        A: fifty-fifty chance of winning either $100 or $0 (nothing), 
OR
        B: fifty-fifty chance to win either $25 or $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 $25 and 50 of them say $35.  Bag B thus guarantees at least $25, 
but the most you can win is $35.  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.
