**continuity correction**is used when you want to use a normal distribution to approximate a binomial distribution.This calculator allows you to apply a continuity correction to a normal distribution to find approximate probabilities for a binomial distribution.

Simply enter the appropriate values for a given binomial distribution below and then click the “Calculate” button.

**Exact binomial probabilities:**

P(X = 3): 0.23040

P(X ≤ 3): 0.92196

P(X 3): 0.68256

P(X ≥ 3): 0.31744

P(X > 3): 0.08704

**Approximate probabilities using continuity correction:**

P(2.5 3.5): 0.23040

P(X 3.5): 0.92196

P(X 2.5): 0.68256

P(X > 2.5): 0.31744

P(X > 3.5): 0.08704
