Will I p this drug test?

I used to smoke marijuana heavily but I havent bought any since the beginning of february. Since then I have smoke on 3 occasions. The first two were at the begining of this month and i only took one or two hits. the second was two weeks ago and i took several hits. Other than those incidents I have not smoked any marijuana. What do you think my odds are of ping a test at lab corp if i chug water and dilute the sample?
