**Apology on rocket failure **

This is a humorous example because when defining probability, improbable outcomes are associated with very small fractional or decimal numbers, eg., 1/1,000,000 or 0.000001. Hence the idea of an

enormousimprobability is a contradiction (probably the writer was thinking of the denominator of a fraction, rather than the value of the fraction). This can be a good start for discussion of very large and very small numbers anywhere in the mathematics curriculum or very large and very small probabilities still lying between zero and one.
