When approximating a binomial distribution with a normal distribution for a binomial random variable X, the continuity correction factor is used. For P(X ≥ 5), the correct continuity correction is to look for the area under the normal curve to the right of 4.5. This accounts for the fact that the binomial distribution is discrete, while the normal distribution is continuous.
