Trevor performed an experiment in which he randomly pulled a card from a standard deck, recorded the card's value, returned the card to the deck, and repeated. His results are shown in the following dot plot, where 11 represents a jack, 12 represents a queen, 13 represents a king, and 14 represents an ace. A dot plot. There is one dot for every number except the following: 4 has 3 dots, 7 has 2 dots, & 12 has 4 dots.
