Answer:
about 0.6903
Explanation:
You want the probability that 70 or more of 110 incoming freshmen will graduate in 4 years if the probability that one will do so is 0.654.
Binomial distribution
A suitable calculator can evaluate the binomial CDF for you. the probability that 69 or fewer will graduate is about 0.31, so the probability that 70 or more will graduate is about 0.69.
p(X ≥ 70) ≈ 0.6903
