black. You will draw two balls from the bag without replacement, one at a time. You lose the game if exactly one of the balls is black (so if you draw two, you still win). What is the probability of winning this game? b) How many three letter words can you make out of the letters of the word MATHEMATICS? How many words can you make that are made entirely out of unique letters? How many words contain the letter T?
