Answer: The probability is P = 0.32
Step-by-step explanation:
Here i guess that the question is: "what is the probability of randomly selecting a seventh-grader".
The data that we have is:
We have 250 sixth graders, 225 seventh graders and 275 eight graders, this adds to a total of 700 options.
The probability of randomly selecting a seventh-grader is equal to the number of seventh-graders divided the total number of possible options, in this case, 700.
So we have P = 225/700 = 0.32
This means that the probability of randomly selecting a seventh-grader is equal to 0.32
