There are three possibilities for the flop. All the same cards, two cards the same and all three different. A study has shown that the probability of them being all different is 41%, that two will be the same is 55% and all three being the same is 4%. (This surprised me, as I expected all three cards to be different to be higher that two the same). If you do get suited hole cards, unless they are high suited connectors, you're better folding. If the flop misses all three and there are two cards the same as your hole cards, you still have odds of 4/1 against making your flush.
