it would be better if you explained how you got .45 for Ar for those people who are not familiar with stats. I understand but for the average person who is learning stats this is useless info if you do not explain or show how the numbers are obtained

I agree. However it’s 150/300 for exposed and 10/300 for unexposed. 0.5- 0.033= 0.4667

@@sophiaechevarria4387 wrong. It's 150/300 - 10/200 which is 0.5-0.05 = 0.45. Then 1/0.45 is ~2.22 which means NNH is 3 if rounding up.
