I drank water more than once. Tell me how many times.

X is the amount of water you drank in the previous reference. XBAR is the average of all the drinks. XTOT = total amount drank.

The total number of drinks is:

N = XTOT / XBAR

The ratio of the first to total number is:

1 / N.

.... Your useless blather ...

I asked "Tell me how many times." You did not do so. Keep proving that you are a trolling idiot.
