Students in the 7th and 8th grade at Imawinner Middle School are going on a field trip to the planetarium. If a student actively participates in the engagement activities at the planetarium, they are entered into a raffle to win a free lunch from their favorite restaurant. The table below shows the number of students in each grade and homeroom who engaged in the activities.
Table"
Homeroom A has 8 7th graders and 9 8th graders
Homeroom B has 10 7th graders
10 8th graders
Homeroom c has 7 7th graders 9 8th graders
Answers:
A 10/53
B 20/53
C 33/53
D 20/53
what is the correct answer choice A b c or d?
The correct answer is C) 33/53.
This is calculated by adding up all the students who engaged in the activities in each homeroom:
Homeroom A: 8 (7th graders) + 9 (8th graders) = 17 students
Homeroom B: 10 (7th graders) + 10 (8th graders) = 20 students
Homeroom C: 7 (7th graders) + 9 (8th graders) = 16 students
Adding up all the students who engaged: 17 + 20 + 16 = 53
Therefore, the probability of a student who actively participated in the engagement activities being chosen in the raffle is 33/53.
