Answer:
The probability of winning a prize is the number of tickets held by the person divided by the total number of tickets.
Explanation:
Andy holds 1 ticket, so his probability of winning is 1/200.
Joe holds 9 tickets, so his probability of winning is 9/200.
Sam holds 4 tickets, so his probability of winning is 4/200.
Therefore, Andy has the lowest probability of winning, Joe has the highest probability of winning, and Sam has a probability of winning that is in between Andy and Joe.
