Question 1069500: It is estimated that on a professor’s statistics exam, three-fifths of the students pass. Suppose a class has 53 students.
What is the probability that at least 35 students pass?
- p(x) = c (53)
x (3/5)^x ✕ (2/5)^53-x

What is the probability that at most 38 students pass?
In this particular exam, find the expected value and the standard deviation.
