I have a grid of 16 tiles face down. Half are good outcomes and half are bad outcomes. How would I calculate the probability of picking x number of Good outcomes before y number of bad outcomes are picked.

Once a tile is selected and it’s state is revealed (good or bad), it is left face up. That is to say there are no replacements. Also order dose not matter.
