I would would say 7.
Mom + Dad + daughter + daughter + daughter + daughter + plus one brother = 7
Since they are all sisters and it says each one has one brother I think that would mean 7. That's just my comprehension of the question, though I may 100% wrong.
Answer:
The provided statement is not a binomial experiment.
Step-by-step explanation:
Four conditions of a binomial experiment:
There should be fixed number of trials
Each trial is independent with respect to the others
The maximum possible outcomes are two
The probability of each outcome remains constant.
For example:
Binomial distribution: Asking 200 people if they ever visit to new york.
Not Binomial distribution: Asking 200 people how much they earn in a week.
Now, observe the provided information:
We need to determine that, asking 100 people which brand of car they drive is a binomial experiment or not.
Clearly it is not a binomial experiment because the maximum possible outcomes are not two.
Therefore, the provided statement is not a binomial experiment.

Answer:
20
Step-by-step explanation:
617/28= 22 (rounded too)
617/32= 19 ( rounded too)
19-22 is teh amount of classes that can be filled with 28 to 32 students.
20 is correct because it is around the amount of classes that there can be. !4 is too little so the number of students should be smaller.
30 and 60 classes are to big. there would only be about 10 or 20 kids per class
