To determine how many '1's in the sequence are followed immediately by a '2' that is not immediately followed by '3', you would need to analyze the sequence directly. For each '1', check if the next character is '2' and ensure that the character following '2' is not '3'. Count each occurrence that meets these criteria for the final answer.
By "and", I don't think you mean "with". For a normal cubic die, 3 2s is 1:63−1 and 2 4s is 1:62−1.
