Instructions for one round - The Additions Task


{% endblock %} {% block content %}

  • In each round, the performer had 45 seconds to perform as many additions as possible (out of seven) for their assigned decider.

  • Each addition consisted of three two-digits numbers. One example is below:

  • 21 + 35 + 48 = 'enter here'

  • The performance of the performer affected the decider's earnings in a specific way. In particular, the total number of questions that the performer answered correctly (out of the seven) determined the lottery that got assigned to the decider. This lottery led to either one of two outcomes (high and low). An example is given below.

  • Number of correct answers by performer led to Lottery earned by the Decider
    0 correct answers --> with 20% probability the outcome is ₹500;
    with 80% the outcome is ₹0.
    1 correct answer --> with 30% probability the outcome is ₹500;
    with 70% the outcome is ₹0.
    2 correct answers --> with 40% probability the outcome is ₹500;
    with 60% the outcome is ₹0.
    3 correct answers --> with 50% probability the outcome is ₹500;
    with 50% the outcome is ₹0.
    And so on.

  • To help you read the table above, consider the second row of the table. It means that if the performer solves one correct addition, then the decider gets assigned a lottery where there is a 30% chance that the decider earns ₹0 and a 70% chance that they earn ₹500. For further clarity please look at the picture below:

  • Remember that the performer had 45 seconds to solve the additions after which the decider got to know his/her earnings (outcome) from the lottery.

  • You will get to see the outcome of the lottery (for example above it will be either ₹0 or ₹500), that the decider earned due to the performer for 10 different rounds.

  • We will then ask you some questions regarding this interaction between the performer - decider pair for each of the 10 rounds.
