Gary and John are playing a game. Gary is going to randomly pick an integer from 1 to 4 (inclusive) and John will randomly guess which number Gary has picked. One possible outcome of this game is (1,3): Gary picked 1, and John guessed 3. Assume all the outcomes are equally likely. 2. Define the following events: A: The summation of picking and guessing number from outcome is greater than 4 B: John correctly guessed Gary's number C: John guessed...
