Answer:
0.11.
Step-by-step explanation:
From the given table it is clear that,
Probability that the selected seventh grader takes the bus = 0.44
Probability that the selected seventh grader drop off by parents = 0.12
Total probability of seventh Grader = 0.56
Probability that the selected eighth grader takes the bus = 0.11
Probability that the selected eighth grader drop off by parents = 0.33
Total probability of Eighth Grader = 0.44
Therefore, the selected eighth grader takes the bus is 0.11.
