The probability that the ticket& is prize is P(the ticket is prize) = 10/10000 = 0.0001. If a person has two tickets then the probability to win the prize is P(to win the prize with two tickets) = 2·P(the ticket is prize) = 0.0002. Therefore, the probability of not getting a prize is P(the probability of not getting a prize with two tickets) = 1 - P(to win the prize with two tickets) = 1 - 0.0002 = 0.9998.
