"What is the probability of flopping a 4-flush or an open ended str8 draw on the flop with 10Js?"

It comes down to a 7% probability of flopping a 4-flush draw (and nothing else) and to a 8.5% probability of flopping an open-ended (8-outs) straight draw (and nothing else).

You have a 16% probability of flopping a 4-flush draw or an open-ended straight draw (but nothing else).

If you have flopped the 4-flush draw, the probability of completing to a flush with 2 cards to come is 35%; if you have flopped the open-ended straight draw, the probability of completing with 2 cards to come is 31.5%.
