    Answer:

    hypergeometric

    Step-by-step explanation:

    For each winning ticket, there are only two possible outcomes. Either it is held by a men, or it is not.

    There is a set number of X, and as the number of winning tickets decrease, the probability of a winning ticket being held by a men can decrease or increase. This is a characteristic of the hypergeometric distribution.
