**Graham**, Friday, July 19, 2013 at 7:23amA sequence of coin tosses has a Binomial Probability Distribution Function.

Event probability: π=0.5

Sample Size: N = 60

Mean: Nπ = 30

Variance: σ^2 = Nπ(1-π) = 15

Std. Deviation: σ = 3.873...

So a result of 34 heads lies just outside of one standard deviation of the mean.
