Question

What does the P × C rule suggest as a stopping criterion for task expansion?

a.

The probability of making a mistake (P) should be divided by the cost of the mistake ( C ).

b.

The product of the probability of making a mistake (P) and the cost of the mistake ( C ) should be above a threshold.

c.

The probability of making a mistake (P) multiplied by the cost of the mistake ( C ) should be below a threshold.

d.

The sum of the probability of making a mistake (P) and the cost of the mistake ( C ) should exceed a threshold.

Posted under Human Computer Interaction

Answer: (c).The probability of making a mistake (P) multiplied by the cost of the mistake ( C ) should be below a threshold. Explanation:The P × C rule suggests that if the probability of making a mistake (P) multiplied by the cost of the mistake ( C ) is below a threshold, then stop expanding. This rule helps in determining which tasks need further expansion based on their criticality.
