It's dark, I have 30 socks all loose and not in pairs, 6 red, 4 blue, 10 orange, 8 black and 2 yellow in my drawer.

how many socks must I grab to guarantee a pair?

If you grab 5 randomly (if none match )you COULD get 1 red 1 blue 1 orange 1 black and 1 yellow

   this is the worst case scenario       Now if you grab ONE more sock...it will HAVE to match ONE of those FIVE

     so to GUARANTEE a pair, you will have to grab SIX .
