Math-probability

A bag contains a total of 30 batteries, of which six are defective. Selecting four at random, without replacement, determine the probability that none of the batteries you select are good.

I think it's 2/15, but im not sure if that's correct....

    Prob = (6/30)(5/29)(4/28)(3/27) = 1/1827
