Odds of Winning a Raffle There's a raffle: * 754 total entries in the raffle * 130 will get selected What's the odds that I will get selected? ## 2nd Question: Now, what if I have 4 of the 754 entries? What are my odds then? Can you walk me through the math on this?

Hint: if you have multiple tickets, calculate the chance that you do not win and subtract from $1$. What is the chance that your first ticket loses? Given that it does, what is the chance that the next one loses-how many numbers are left?

Added: to get the chance that you have two winners out of four, you have {6 \choose 2} ways to choose the winners, so the chance is ${6 \choose 2}\cdot \frac {130}{754}\cdot \frac {129}{753} \cdot \frac {624}{752} \cdot \frac {623}{751}$. The others are similar.
