Chance of passing ua test?

Got a test tomorrow. Just a online bought $4 test. 17 days ago I smoked about 1/4 a blunt of decent kush. 9 days after that I smoked about a 1/3 of blunt of kush and 3 hours later took a few hits out of a bowl. I had been clean for 3 months before all of that. The test is tomorrow which means I will have been clean for 9 days. I'm pretty decently skinny. Haven't Burnt any fat in the past few days. Moderately fast metabolism, I plan on diluting tomorrow but what are the chances of passing?
