Sounds like a problem in binomial probability.  What is the probability of picking a rotten orange from this crate?  Once you have this binomial probability, what do you do with it to calculate "the probability that the sample contains 1 or more rotten oranges?  What value should you use for n?  Please look up "binomial probability distributions" in your text or online.
