My place plan yesterday, best day EVER, only backing overs 17 bets for 17 hits. The overall S/R (including unders) is 65% what are the odds of 17 hits in a row?

If anyone is kind enough to do the calculation, I would like to know the % figure for 3 outs in a row i.e. how many times in say 1000 bets will I encounter 3 losses in a row with a S/R of 65%? any help appreciated!
