I read with horror in various national newspapers that people just can’t do simple maths any more. Here’s a simple challenge to sort out the mathematical men (or women) from the boys (or girls):

Prize bonds cost €25 each.

€1000 worth of prize bonds has the odds of 3.6 to 1 of winning a prize in a year.

A prize is at least €75.

Interest in a current account is 3%.

What’s the probability of winning at least the equivalent of interest in a year with €10000 worth of prize bonds?

Not enough information. Depends on the value of all prizes…not just the minimum prize value (€75). Now, if the minimum prize was €300, that would be sufficient.

Y’know someone said that to me, but as the requirement is

at leastgetting interest then the value of the other prizes isn’t important. Still, I worked it out myself in the end and I reckon I should go for it.
