Answer:
The probability distribution of X for this raffle is as follows:
Value of X Probability
$670 1/500
$0 499/500
The probability of winning the $670 prize is 1/500, as there is only one ticket out of 500 that will win this prize. The probability of not winning the prize is 499/500, as there are 499 tickets out of 500 that will not win the prize.
Note that the probabilities in this distribution add up to 1, as is required for any probability distribution.
