My couch potato friend enjoys sitting in front of the TV and grabbing handfuls of 4 chocolates at random from his snack jar. Unbeknownst to him, I have replaced one of the 18 chocolates in his jar with a cashew. (He hates cashews with a passion.)
How many possible outcomes are there the first time he grabs 4 chocolates?
1
How many of these include the cashew?
