Or, Do You Believe This Claim?

New claims are made every day...which by definition, means that the assertions are offered as facts.

For example, consider the following "claim," copied many years ago from some text that I have lost or given away:


For a coin to fall heads 50 consecutive times, it would take a million men tossing coins 10 times a minute and 40 hours a week--and then it would happen only once every nine centuries.


How could this "fact" be supported? That is, what is the probability of 50 consecutive heads?

Do you think that the way the claim as worded is accurate? For example, if the probability of a coin flip producing a head is 1/2, will a head appear in every two flips of the coin?
