Raffle ticket odds, does buying say 10 out of 28,000, give you 1/2800 chance on every ticket or 1/28000?
In: Mathematics
Each ticket will have a 1/28000 chance of winning, but overall you have a 1/2800 chance of winning. You can think about it like this: for each individual ticket, the number of ways that ticket can win is obviously 1 (if that ticket is drawn), and the number of total outcomes is 28000 (there are 28000 tickets, any one of which could be drawn). Probability is really just (number of ways the desired outcome could happen)/(number of total outcomes).
The reason you have an overall chance of winning that’s 1/2800 is because the (number of ways the desired outcome could happen) is now 10. The desired outcome is winning, and the number of ways you win is if any one of your 10 tickets is drawn.
