Depens how many times are you going to be tossing the coin.

It is interesting to note that the question says nothing about more than 5 times IN A ROW. If you toss the coin 6 times the odds are 2 in 64 that 6 of a kind will occur and if you toss it 11 times it is a certainty that 6 of a kind will occur. But what is the probability for 7,8,9 and 10 throws? It seems to me that the questionner should state his question more precisely before we puzzle our heads about it. Addendum - if you toss the coin 9 times you are slightly more likely 260/512 to have 6 heads or 6 tails than not. For 6 Heads in sequence it is 1 in 64 (1.5625%) but it is also 1 in 64 for Tails so therefore 2 in 64 (3.125%) for either.

The mathematical calculations giving about 3% per side are correct, assuming two things. One, that a coin cannot land on its edge, (the third side, which I have flipped it on to before). Two, that the coin flip is fair and random. People always assume these things but never state the assumptions. There are people who can take a coin and flip it to heads each time. Also, there are coins that are unbalanced, so they tend to favor one side or the other.
Theoretically, the math is correct given those assumptions people never state.

Once =.5 (50% chance)
Twice= .5 times .5
Thrice=.5*.5*.5
4x= .5 to the fourth power
5x = .5 to the fifth
6x (your stated minimum) = .5 to the 6th, or approximately 1.56%
This assumes that the required "more than 5 times" is in sequence, rather than being broken by the other side occurring.

The chance of it landing on the same face 6 times in a row is 1 in 32 i.e. 3.125%

5 times would be 1/10 and more than five would be 1/12 for six, 1/14 for seven. This is a pattern just take the number of times in a row and multiply it by two.

As there are only 2 sides to the coin it would be factorial 2 which is 2x1 which means 50%

P(more than 5 heads)
= 1- P(1 head) - P(2 heads) - P(3h) - P(4h) - P(5h)
= 1 - 0.5 - 0.25 - 0.125 - 0.0625 - 0.03125 = 0.03125 = 3 %
P(more than 5 tails) = same = 3%
P(more than 5 of the same face = 2 * 3% = 6%.

1 over 6 to the power of 2
=0.015625
=1.56%
Guys, you're not reading it right it's MORE than five times which is 1/64.
