A Standard Cost Variance is a difference between the actual cost incurred and the standard cost against which it is measured.
The main difference between normal costing and standard costing is that normal costing uses actual costs for material and direct labor costs, whereas standard costing uses predefined costs for these two items. That's it.
This difference between standard cost and actual cost is called variance. An unfavorable variance occurs if the actual cost is higher than the standard.

Answer:

Explanation:
Given
Probability of a person to not enter into a bar or ducking is 
Probability of a person to enter into a bar
(Probability of a person to not enter into a bar or ducking)
Substituting the given value, we get
Probability of a person to enter into a bar

Total three men attempts to enter into the bar and their course of action is independent of each others
