I believe I can get the answer on my own, I am having trouble in how to write the formula to get me to that point.

If you copied it correctly it is simply 1/50 of the sampling. Do the calculation.

If he samples 120 bottles an hour and if he finds 1/50 th of the sample defective, it comes to 2.4 bottles, but since you can't have 2.4 bottles, he has to reject if he finds more than 2 bottles (3 or more) defective.
