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. What is the probability the winner is a 7th grader in Homeroom C? (1 point) Responses 79 7 ninths 725 7 over 25 716 7 over 16 753 7 over 53 Skip to navigation
To find the probability that the winner is a 7th grader in Homeroom C, we need to find the total number of students who participated in the activities and the number of 7th graders in Homeroom C who participated.
Total number of students who participated = 79 + 725 + 716 + 753 = 2273
Number of 7th graders in Homeroom C who participated = 79
Therefore, the probability that the winner is a 7th grader in Homeroom C is:
Number of favorable outcomes / Total number of outcomes = 79 / 2273 = 7/203
Therefore, the probability is 7 over 203.
no
I apologize for the incorrect response. Let's try to solve it again.
The probability that the winner is a 7th grader in Homeroom C can be calculated as follows:
Total number of students who participated = 79 + 725 + 716 + 753 = 2273
Number of 7th graders in Homeroom C who participated = 79
Probability = Number of 7th graders in Homeroom C who participated / Total number of students who participated
Probability = 79 / 2273
Probability = 0.0347 or approximately 3.47%
Therefore, the probability that the winner is a 7th grader in Homeroom C is 3.47%.
ur answer choices-
7/9
7/25
7/16
7/53
To find the probability that the winner is a 7th grader in Homeroom C, we need to calculate the number of students in 7th grade in Homeroom C who participated and divide it by the total number of students who participated.
Number of 7th graders in Homeroom C who participated = 79
Total number of students who participated = 79 + 725 + 716 + 753 = 2273
Probability = Number of 7th graders in Homeroom C who participated / Total number of students who participated
Probability = 79 / 2273
Therefore, the correct probability is 7/253.
round it
If we round the probability 7/253 to the nearest whole number, the probability is approximately 7/36.
So the closest rounded answer choice would be 7/53.
whats the probablity that the winner is NOT in homeroom B
Let's calculate the probability that the winner is NOT in Homeroom B.
Number of students in Homeroom B who participated = 725
Total number of students who participated = 79 + 725 + 716 + 753 = 2273
Number of students NOT in Homeroom B who participated = Total number of students - Number of students in Homeroom B who participated
Number of students NOT in Homeroom B who participated = 2273 - 725 = 1548
Probability that the winner is NOT in Homeroom B = Number of students NOT in Homeroom B who participated / Total number of students who participated
Probability = 1548 / 2273
Probability ≈ 0.6804 or approximately 68.04%
Therefore, the probability that the winner is NOT in Homeroom B is approximately 68.04%.
