28 tickets is sufficient to beat the odds of 1 in 14 million to win the jackpot? yes, but those aren't the odds in question

Does the number needed vary according to your personal age? yes, among other things So different people need different quantities? very much so :)

Do you need to buy the 28 tickets every week? Twice a week? Is there a relevant other use of the same sum?

Do you need to buy the 28 tickets every week? no - the idea is that if I were ever to buy lottery tickets, I would need to buy 28 of them so that... Twice a week? Is there a relevant other use of the same sum? I am not quite sure what this means. The puzzle isn't about some other purpose to which I could put twenty eight quid.

Is the important thing the expected return on 28 tickets as compared to fewer?

Is the important thing the expected return on 28 tickets as compared to fewer? to an extent - 28 tickets are needed to increase the expected return to a certain level

So a higher level is needed when you are older? Because you have fewer years in which to earn money? Because you will retire sooner? Have less of a chance to save money for retirement?

Would you have to buy 28 tickets at once? once in a time? repeatedly?
If you buy 28 tickets at once, do they participate in the next drawing only? in the next 2 drawings? in a series of ... drawings?
are these subscription tickets? (= they take part in any drawing from the moment you buy them, until you cancel the subscription)

Would you have to buy 28 tickets at once? I could do this once in a time? or this, as long as when the draw was made, I had 28 tickets repeatedly? I would need 28 tickets every time the lottery was drawn, but there would be no compulsion for me to buy tickets for every draw
If you buy 28 tickets at once, do they participate in the next drawing only? this one in the next 2 drawings? in a series of ... drawings?
are these subscription tickets? (= they take part in any drawing from the moment you buy them, until you cancel the subscription) no - these are one-shot tickets for a single drawing of the lottery

Is the relevant thing the expected number of years you have left to live? So if two people of different ages, genders, occupations, etc. are both expected to live for 30 more years, they would both have to buy the same number of lottery tickets?

If a decision were made today by the people in charge of the English lotteries that the English lotteries would cease at the end of the year 2015, would that change the number of tickets you have to buy? Would it change the number of tickets that I would have to buy?

Is it relevant whether the jackpot, should you win it, is paid as a lump sum or as an annuity? If so, which?

Does the number of tickets you need to buy depend on your current financial situation? Does it depend on the state of your health? Does it depend on the age at which you are allowed to retire in order to receive your pension?

If the cost of lottery tickets and the amount of the prizes were all divided by 100, would you still have to buy 28 tickets? or 2800? or some other number?

There is a sort of lottery of postcodes as to whether people get the best health care in the NHS. Is this meant as a comparison along the lines of "You have as much chance winning the lottery with n tickets as getting the best treatment (at your age) for your condition in the area where you live"?

Is it something along the lines of living long enough to collect your prize? So you need to buy 28 tickets in order that your chance of winning a jackpot not be significantly reduced by the chance that you will die before you have the opportunity to collect it?

Is it something along the lines of living long enough to collect your prize? So you need to buy 28 tickets in order that your chance of winning a jackpot not be significantly reduced by the chance that you will die before you have the opportunity to collect it? this is easily close enough - well done :)

***** SPOILER *****

A friend of mine who is an actuary recently informed me that there are about a million men my age or thereabouts in England, and that two of them die every hour. This is the kind of cheerful conversation that actuaries have with their friends down the pub.

A few moments' reflection indicated that my chance of dying during any given hour in the near future was approximately 500,000 to one against.

The chance of winning the jackpot on the National Lottery is roughly one in 14 million with a single ticket. If you buy 28 tickets (with different numbers on all of them, bien entendu) the chance of winning the jackpot reduces to roughly one in 500,000.

If I were to buy lottery tickets and settle down to watch the draw live on television, I would need 28 of them in order that the chance of my winning the jackpot equalled the chance of my dying while watching the programme. This depressed me somewhat.

More cheerful puzzles on the way. Thanks to all who took part in this one :)

Well, what "may" look non-mathematical is that the chance should be reduced from 1:14000000 to 1:500000... :)
