Well no.

Every coin toss takes place in a vacuum. The chances of every toss are essentially 50/50.

I say essentially because the coin will tend to land a little more often on the side that is up when it was flipped.

If they "spun" the coin rather then toss it chances are the result will be tails.

Flip a coin and tell me how many tosses it took for you to run six consecutive outcomes.
