tosses: 10

heads: 6

x: 1.92

Degrees of Freedom: 1

Result: 16.6%

1) Does this mean that the probability of 6 heads in 10 tosses is less than 16.6%?

2) Why doesn't this test take the number of tosses into account? What is the degree of confidence?

3) Bottom line is that I want to know if the coin is fair. How many tosses do I need and what is the result that I'm looking for?

Thanks.
