Students in the 7th and 8th grade at Imawinner Middle School are going on a field trip to the aquarium. If a student actively participates in the engagement activities at the aquarium, 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.
7th grade, homeroom A is 8, homeroom B is 10, homeroom C is 7,
8th grade homeroom A is 9 homeroom B is 10 homeroom C is 9
Total number of 7th grade students who engaged: 8 + 10 + 7 = 25
Total number of 8th grade students who engaged: 9 + 10 + 9 = 28
Total number of students who engaged in the activities: 25 (7th grade) + 28 (8th grade) = 53
Therefore, there are 53 students in the 7th and 8th grade at Imawinner Middle School who actively participated in the engagement activities at the aquarium.
What is the probability the winner is a 7th grader in Homeroom C?
7/9
7 over 25
7 over 16
7 over 53
The probability that the winner is a 7th grader in Homeroom C would be calculated as follows:
Number of 7th graders in Homeroom C who engaged: 7
Total number of students who engaged: 53
So, the probability would be: 7/53
Therefore, the correct probability is 7/53.
I need the correct answer
The correct answer is:
7/53
What is the probability the winner is NOT in Homeroom B?
10 over 53
20 over 53
33 over 53
10 over 53
To calculate the probability that the winner is NOT in Homeroom B, we need to determine the number of students who are not in Homeroom B and engaged in the activities.
Number of students who are not in Homeroom B and engaged = Total number of students who engaged - Number of students in Homeroom B who engaged = 53 - 10 = 43
Therefore, the probability that the winner is NOT in Homeroom B is 43/53.
