A student claims that if a fair coin is tossed and comes
up heads 5 times in a row, then, according to the law
of averages, the probability of tails on the next toss
is greater than the probability of heads. What is your
reply?

No matter what comes up or how often you get heads, the chance for each individual throw is always the same -- 1 chance out of 2.
The previous tosses do not effect later tosses; they are independent.
