{{ block title }} Experiment Overview {{ endblock }} {{ block content }}
In each trial, the computer will select one of two boxes filled with marbles: Yellow and Green. The probability of selecting the Yellow box is 90%, and selecting the Green one is 10%. The Yellow box has 3 yellow marbles and 1 green marble, while the Green box has 3 green marbles and 1 yellow marble. Then, the probability of a single yellow marble is equal to 75% if the box selected was Yellow, and 25% if the box selected was Green. After the computer selects a box, you and another participant will observe the same sequence of 10 marbles coming from that box. The computer will draw a sequence of marbles, recording the color and replacing the marble in its box after each draw.
The sequence size, the share of marbles, and the probability of selecting each box will remain fixed throughout the experiment. The next table summarizes the probabilities associated with each box:
| Box | Probability computer selects each box | Number of yellow marbles | Number of green marbles | Probability of drawing one yellow marble |
|---|---|---|---|---|
| Yellow | 3 | 1 | 75% | |
| Green | 1 | 3 | 25% |
