I get about 1 in 15,800. And for the probability of getting at least 49 heads in 67 tosses, I get about 1 in 10,300.

Still trying to figure out how lucky that new customer is?
I have no idea how to calculate it, but, Chester probably didn't factor in the one tie you indicated in your other post. So assuming his number is correct for 49/67, the odds come down a little for 49/67/1.

The wizard's answer is correct, as usual, however this is a simple application of the binomial distribution and Excel also has a function for this distribution: BINOMDIST(number, trials, probability, logical). Logical is 1 if you want the cumulative distribution and 0 if you just want the binomial weight.

according to your new 'ask the wizard' the odds aren't 50-50!
