A lottery has 5 balls numbered 1 to 5.  We are interested in the first ball chosen.  These are the numbers of the first ball drawn in 13 lottos: [1, 3, 4, 3, 1, 5, 2, 3, 3, 1, 4, 1, 3].  Which of the following is a correct frequency chart showing the frequency of each ball, with a right-hand axis that shows estimated probabilities?

This is continuous data.
