Let x be a binomial random variable with n=20 and p=.8.If we use the normal distribution to approximate probabilities for this, a correction for continuity should be made.To find the probability of more than 12 successes, we should find ___. A)P(x>12.5) B)P(x>12) C)P(x>11.5) D)P(x<11.5) E)P(x < 12)

When using the normal distribution to approximate probabilities for a binomial random variable, a correction for continuity should be made by adding or subtracting 0.5 to the value of x. To find the probability of more than 12 successes, we should find P(x>12.5).
