David has the letter tiles in a bag. He reaches in the bag and pulls out an O. He then puts the tile back in the bag. If David randomly selects a tile from the bag, what is the probability he will select an O again?
Explanation
By placing the O back in the bag the probability of picking an O resets. Because there are 8 total tiles and 2 letter O's, the probability is 2/8 or 1/4.
