Of all 3 to 5year old children, 56% are enrolled in school (p=0.56). We are looking at a sample of 500 (n=500) such children, and this is thought to follow a binomial distribution. Use the normal approximation to the binomial to find the probability that at least 300 of those children will be enrolled in school P(X ≥ 300)
