A contribution value necessary for achieving a target accuracy from a correct answer probability of each participant is calculated, a contribution value of the participant is added for an answer in accordance with the calculation, and it is set at a condition for determining completion of a task, that is, determining that a correct answer is obtained and no additional participant is necessary. The contribution value is calculated as the inverse of the number of participants at which the target accuracy is reached with a predetermined correct answer probability. The contribution value of the participant is added to the contribution value for the task in which that participant participates. At the time when the sum of the contribution values for a task exceeds one or when one option is certain to be a correct answer, the result having the largest sum of the contribution values is output. |
