A junior high principal runs a report to determine what ratio of all 100 students take the bus to school or are dropped off by parents, based on grade (seventh grade or eight grade). The results are shown in the following probability distribution table.
Grade vs.
Transportation Takes
Bus Parents
Drop off Total
Seventh Grader 0.44 0.12 0.56
Eighth Grader 0.11 0.33 0.44
Total 0.55 0.45 1
What is the probability that a student is in seventh grade, given that he/she is dropped off by parents?
0.27
0.38
0.22
0.73

The probability that a student is in seventh grade, given that he/she is dropped off by parents is option C) 0.22

Step-by-step explanation:

P(student is in 7th grade student is in seventh grade) = P(students in 7th grade) / P(7th grade students dropped by parents).

⇒ 0.12/0.56

⇒ 0.22

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
