At the beginning, which range of numbers is more likely to be the chances that James and Calie have two girls:
between 0% and 50%(i.e., at most one half) VS between 51% and 100%(i.e., more than one half) of the chance?
If you choose “between 0% and 50%”, it means you think it is more likely that there is 0% ~ 50%(i.e., at most one half) of the chance that James and Calie have two girls.
Then, the computer will further say “Let’s zoom in on 0 ~ 50” and asks which narrower range is more likely to be the chances that James and Calie have two girls:
between 0% and 25%(i.e., at most one quarter) VS between 26% and 50% (i.e., more than one quarter but at most one half) of the chance?
If you chose “between 0% and 50% (between 51% and 100%)” and then clicked on “EXIT”, the computer will randomly select a card from a deck of cards labeled 0% - 50% (51% - 100%), and submit it as your guess on the chance that James and Calie have two girls for you.
Here is an example of how the task and procedure proceeds to give you an overview of how things work.
EXAMPLE:
James and Calie are a married couple. They have two children. Assume that the chance of each gender is 1/2. What is the chance that they have two girls?
