Statistics Quiz#1


OK, here's an off-season challenge for the stats gurus here on CD:

A computer equipped with a quantum noise random number generator is programmed to perform the following experiment: It flips a biased coin 2000 times and records the number of heads for that experiment. The coin is biased so that it is twice as likely to come up tails than heads for any given flip.

If the computer were to perform 100 of these experiments, what is the probability that more than 59 of those 100 experiments would each have fewer than 672 heads?
