The probability that the first one is bad is simply 4 divided by 34 which reduces to 2/17.
The probability that the second one is bad, presuming that the first one was bad, is 3 (one less because the first one picked was bad) divided by 33 (one less because no replacement, which reduces to 1/11
The total probability is the product of the two fractions, i.e. 4/187. Or, in the common vernacular, when pigs fly.
