excel中6个独立事件的概率

Question

I want to calculate the probability of 6 independent events in excel. I know the general formula to do this howver it is very cumbersome to implement in excel.

Is there a better way?

Answer 1

The equation in your question suggests that you are asking for the probability of one or more of the events happening. This is the same as asking for the probability of "not none of them" happening. In Excel, you can calculate this using the following formula:

=1-PRODUCT(1-A1,1-A2,1-A3,1-A4,1-A5,1-A6)

(Here I am assuming that the probability of the events are given in cells A1:A6 .)

However, if instead you are asking for the probability of all of the events happening, it's just the product of their individual probabilities:

=PRODUCT(A1,A2,A3,A4,A5,A6)
