A stockiest has 20 items in a lot, out of which 12 are non defective and 8 defective. A customer selects 3 items from the lot, what is the probability that two are non defective and one is defective?

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
