How do you use the AVERAGEIFS function in Excel?
To find out an average of certain numbers, you can supply them directly in your excel average formula. Average of two numbers is given by the sum of the two numbers divided by two. =averageifs (b:b,b:b,>=90,b:b,
What is the probability formula?
The probability formula is defined as the number of favorable outcomes divided by the total number of outcomes. P (A) = Number of favorable Outcome Total Number of Favorable Outcomes P (A) represents the probability of an event, n (E) represents number of favorable outcomes and n (S) represents total number of events.
