Ryan spent a dollar on a TriState Megabucks ticket, enticed by a big jackpot. Ryan chose six different numbers from 1 to 40, inclusive, hoping that hey would be the same numbers draw later by lottery officials. Sad to say, none of Ryan's choices were drawn. What was the probability of this happening? The order in which numbers are drawn is of no significance.
Thank you !

34/40 * 33/39 * 32/38 * 31/37 * 30/36 * 29/35 = ?
