I am trying to write a formula to calculate percent chance of having a winning raffle ticket. Lets say for example there are 1430 tickets sold. I have 64 tickets. Lets say there are 25 prizes.
I was thinking number of tickets I have divided by the total of tickets. Then multiply that by the 25 prizes. Then multiply by 100 to get a percent. Something doesn't seem right thou with this formula but I'm not sure.
Thanks
