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?

The coin has no idea what the result of previous tosses was. The probability of heads on the next toss is 0.5 unless it is an asymmetrical coin.
