This table shows how many sophomores and juniors attended two school events. A student is selected randomly from this group. Jazz band concert | Volleyball game | Total Sophomore | 35 | 42 | 77 Junior | 36 | 24 | 60 Total | 71 | 66 | 137 What is the probability that the student attended the jazz concert, given that the student is a sophomore? Round your answer to two decimal places. A. 0.55 B. 0.45 C. 0.49 D. 0.26
