Age | Cola | Root Beer | Orange | Totals Under 21 | 45 | 25 | 25 | 95 21-40 | 33 | 27 | 41 | 101 Over 40 | 18 | 31 | 38 | 87 Totals | 96 | 83 | 104 | 283 (a) If one person is randomly selected, find the probability that the person is under 21 or prefers orange soda. (b) If one person is randomly selected, find the probability that the person chosen prefers root beer given that they are over 40. (c) If one person is randomly selected, find the probability that the person is a 21-40 and prefers root beer.

The graph shows the number of sodas (soft drinks) adolescents (age $12-19$ ) drank per week from I99 $1-2006 .$ G( $x$ ) gives the number of sodas for girls, $B(x)$ gives the number of sodas for boys, and $T(x)$ gives the total number for both groups. Use the graph to do the following. (GRAPH CANNOT COPY) Use the slopes of the line segments to decide in which period (1991-1996 or $1996-2006$ ) the number of sodas per week increased more rapidly.
