Since n p 5 and n q 5 use the normal approximation to the binomial. The problem is that the binomial distribution is a discrete probability distribution whereas the normal distribution is a continuous distribution. The normal approximation to the binomial distribution for 12 coin flips.
Normal Approximation to the Binomial Distribution.
It could become quite confusing if the binomial formula has to be used over and over again. Y N 159 86447. The smooth curve in Figure PageIndex2 is the normal distribution. Suppose 16 Coins Are Tossed Find The Probability Of Getting The Following Result Using The Binomial Probability Formula And The Normal Curve Approximation.
