No, Pam will not succeed.
Step-by-step explanation:
Pam will not succeed in the case in which she had sued the lottery office for claiming her lottery money which she had won. The reason for this is that she had lottery ticket.
And the rules of the contract of the lottery say that the ticket of the lottery must be shown if the amount of the lottery has to be claimed by the winner. Since Pam had accepted that rule when she had entered in to the contract, so now she has no right to sue the lottery office.
