You can put this solution on YOUR website! of all 3 to 5 year old children, 56% are enrolled in school. If a sample of 500 such children is randomly selected, find the probability that at least 250 will be enrolled in school.
----
Binomial Problem with n = 500 and p = 0.56
--------------------
P(250<= x <=500) = 1 - P(0<= x <= 249)
---
= 1 - binomcdf(500,0.56,249) = 0.9969
