You flip a fair coin 20 times in a row and it comes up heads every
single time. You flip the coin one more time. What is the probability of tails on this last flip?

Since you are flipping a fair coin and each of the probabilities is independent (what you flip the first time doesn't effect what you flip the second third or fourth times) it the same as asking what is the probability of flipping tails one time.
Probability = # of positive outcomes/ # of total outcomes
Hope this helps. Good Luck.

A statistician at Harvard, Dr Persi Diaconis, regarded into this. It seems that in case you turn a coin a particular way, it comes up an identical way regularly. that signifies that in case you instruct any favoritism in how the coin starts (heads up or tails up), you'll see a patter contained in the outcome.

It's 50/50.....everytime you flip it, it's 50/50.....there are only two sides, so it has to one or the other. Unless it's a trick coin. ;-)

It's still an individual toss and has nothing to do with what happened previously.
