Probability of loosing 3 straight coinflip or better situations

[arod15]

Down to heads up i have 8150 and Villian has 1850 at a 50+5. I get A 10 and Villian pushes i call he has q10 and hits a queen. Now i have 6300 and he has 3700. I get A6 and he moves in again i call and he has K3 hits a 3 on me. Now he has 7400 to my 2600 i then get AQ and move in he calls with A 10 and hits his 10. What are the odds? PS im not complaining i had a great session just curious to know the prob of that happening.
