It would actually be no solutions, since an equation can't have more than one equal sign xD
If we round it
1) 7 people
2) 4 people
3) 5 people
Answer:
a) The probability that exactly 17 of them enroll in college is 0.116.
b) The probability that more than 14 enroll in college is 0.995.
c) The probability that fewer than 11 enroll in college is 0.001.
d) It would be be unusual if more than 24 of them enroll in college since the probability is 0.009.
Step-by-step explanation:
We can model this with a binomial distribution, with n=29 and p=0.65.
The probability that k students from the sample who graduated from high school in 2012 enrolled in college is:

a) The probability that exactly 17 of them enroll in college is:

b) The probability that more than 14 of them enroll in college is:

c) Using the probabilities calculated in the point b, we have:

d) The probabilities that more than 24 enroll in college is:

If you already have any two sides of a right angle then the Pythagoras theorem would help.
It goes like (Hypotenuse)² = (Side A)² + (Side B)².
