The table shows the number of games in which a basketball team's total score was within each of five ranges of points.
Using the data in the table, complete the predictions about the number of points the team will score in its next game.
Scoring 96-105 points in the next game is (a) scoring 136-145 points in the next game.
Scoring 116-125 points in the next game is (b) scoring 106-115 points in the next game.
