One or more answers were incorrect. The highlighted questions need to be corrected. Remember:
Every point you save becomes a lottery ticket.
You win €5 if the random number drawn is equal to or less than your tickets.
The payoffs and probabilities of the options are fixed throughout the task.
Task Instructions
Welcome! You will participate in a task that lasts for 30 rounds.
How It Works
In each round, you will choose one of three options: A, B, or C.
Each option works like a slot machine with two possible outcomes:
With some probability, you win a fixed number of points.
Otherwise, you win nothing (0 points).
Each option has its own fixed probability and its own fixed payoff. These values stay the same throughout all 30 rounds, but they are hidden from you. Your job is to figure out which option is best by trying them out.
Example (for illustration only — not the actual values):
Suppose one of the options had these hidden values:
Win Probability
Payoff When You Win
60%
15 points
This means each time you choose this option, you have a 60% chance of winning 15 points and a 40% chance of winning nothing (0 points).
Each of the three options in your task works this way, but with its own hidden probability and payoff.
€5 Personal Lottery
Every point you save in this task becomes a lottery ticket.
At the end of the task, the computer will draw a random number between 1 and 5,000.
If the random number is equal to or less than your total number of tickets, you win €5.
If the random number is higher, you win nothing.
The more points you save, the more tickets you collect — and the better your chance of winning.
This is your individual lottery — your result depends only on your own performance, not on other participants.
