Hi guys, new to the forum.
Just wondered if anyone could help me with some basic probability. I used to think I was pretty good at maths, but I was recently helping my daughter with her maths homework and found I was confusing myself and questioning what I was trying to teach her.. I guess modern technology has made my brain lazy over the past 2 decades!
In basic terms, I was using the lottery as a means of explaining the odds of winning a prize. Using the UK Thunderball game as an example shown here https://www.national-lottery.co.uk/games/thunderball/game-procedures I was explaining the 1 in 111 chances of matching 3 numbers to win £10. My daughter then asked.. if you bought 111 tickets would you be guaranteed a £10 prize? To which I confidently answered 'yes, assuming each ticket held a different combination of numbers'
I have since questioned my response, as it doesn't logically add up in my head, and I've struggled to find a simple equation to prove or disprove it.
In the game mentioned above, you chose a line of 5 numbers between 1 - 39. There must be a simple way of working out how many lines would guarantee matching 3 numbers?
I know this will be very basic compared to the standard you guys are at here, but can someone kindly help me put my mind at rest here!? Feeling a bit dumb!
