Question

It is a pleasant day (or there is wind anyway) and instead of sitting in statistics class three students decide to go sailing. Upon arriving at the boat however, they discover that it is too dark below decks to clearly see the sails. Knowing that there are 3 jibs, 5 mains and 2 spinnakers on board, if each student goes below once and returns with a randomly picked sail, what is the probability that 2 or fewer jibs will end up above decks
