At a small college it is known from previous years that 35% of all college freshman start in college algebra. The new freshman class has 100 students in it,
What is the probability that between 35 and 42 freshman will start in college algebra?
Is it reasonable to approximate this distribution using a normal curve? Why or why not?
What is the probability that at most 24 students will starting college algebra?
What is the probability that at least 48 students will start in college algebra?
This college tries to kep class size down to 24 studentsfor freshman. Why might the probabilities in the previous 2 questions be important to know?
Sixty percent of the students at a particular community college are female.
If 12 students at that community college are randomly selected,
find the probability that 5 will be female.
