The monthly prize fund is currently calculated at one twelfth of 1% of
all the bonds currently issued, ie the annual return is 1% on average.


Currently, the chance of a £25 prize is 1 in 34,500. That is for one bond.

Jim has 15,000 bonds, so he has been rather lucky to have won several
months in a row. With that holding, his chance of winning £25 in any
month is 35.3%.

Jim claims to have won 5 months in a row this year, IIRC, which has a
probability of 0.5%, ie 1 in 200.


what do you mean claims?????
