how many will he have to draw before being sure he has a matched pair of tennis shoes? Also, how many will he have to pull to be sure he has all teh tennis shoes?
Sam has 8 pairs of leather shoes %26amp; 6 pairs of tennis shoes. If he pulls shoes out of his dark closet randomly,
From the way I see it, it is entirely possible (though not probable) that the first 16 shoes he pulls out of his closet will be leather shoes. Therefore, he would have to pull out 18 shoes to be certain that he even has two tennis shoes, and there is nothing to guarantee that he has a pair of tennis shoes. It is also possible (though not probable) that the first 6 tennis shoes he pulls out are all the left shoe. So, he would need to pull out 23 shoes before he would be able to be certain that he had a matching pair of tennis shoes. Especially since it's also not stated that all of these shoes are exactly the same. In fact, it's likely they aren't the same, so he'd need to pull enough to make sure that he could have a matching pair. So, 23 seems like the answer.
Since I already stated that it's possible to pull out all 16 leather shoes before tennis shoes, he'd have to pull out all 28 shoes to be certain he has all the tennis shoes.
