ODDS: Flopping an open-ended straight draw!

[miamikid]

I have different maths and calculations.

Would someone please show me the proper math in calculating the odds of flopping an open ended straight draw using both of your hole cards (54 to JT).

Thanks!

You'll get better answers if you post this in the *Probability* forum.
