Important: If you answer any of the below questions incorrectly, the study ends after this page and you will receive your participation payment, but you do not qualify for a bonus.
Suppose there are 70 "Bag A" cards and {% if player.bags_first == 2 %}30 "Bag B" cards{% else %}3 cards for each of the Bags B, C etc. up to J{% endif %} in the deck. Further suppose there are more red balls in Bag A than there are red balls in {% if player.bags_first == 2 %}Bag B{% else %}the Bags B, C etc. up to J{% endif %}. Next, one red ball is drawn from the secretly selected bag. {% if player.bags_first == 2 %} You are asked for the likelihood that the secretly selected bag was Bag A rather than Bag B. {% else %} You are asked for the likelihood that the secretly selected bag was Bag A rather than any of the Bags B, C, etc. {% endif %}

Suppose that in a given task you guess that the probability that Bag A was selected is 70%. Further suppose you are 60% certain that the optimal guess is actually somewhere between 69% and 71% (close to your guess). Please select the appropriate button below to indicate this level of certainty.
