The following is some good information on outs and probabilities, taken from the following two web sites (modified slightly by Yours Truly for clarification):

Number of outs for specific draws:
Flush draw with two overcards or a straight-flush draw_____15 outs
Flush draw with one overcard_________________________12 outs
Flush draw_________________________________________9 outs
