The answer is "none of the above." If there are 32 red gloves and 25 yellow gloves it's possible she could pull all the reds and yellows without getting a single blue - that would be 57 gloves. At this point there are only blues left. So she is guarranted to get a blue pair by taking two more gloves. So the total is 32+ 25 + 2 = 59.
I have a feeling that you mistyped the problem, as it seems the hats have nothing to do with anything. |
