I did a line Thursday night, one line Friday, and about three bumps throughout the day Saturday. The last bump was at latest 12 am. I got randomly drug tested Wednesday morning around 9:30. It was about 82 hours (there was a time change so I added an extra hour) between the last bump and the time of my test.

I did about two grams the Friday and Saturday before but was clean until the next Thursday. That may be important, I'm not sure.

Also, I am 5'6 and weigh about 110lbs so I have a fairly fast metabolism. I also worked out the Tuesday night before the test and drank a fair bit of water.

What is the probability the coke will show up?

Thank you for your help.
