The binomial distribution approaches normality as N increases. Explain how this relationship useful for solving binomial problems involving N>20. What are the advantages and disadvantages of this approach.
You are using the binomial distribution to determine the probability of obtaining a result as extreme or more extreme than 10 P events in a situation where N=12 and p=0.40. you look up the probability of 8,9, 10 Pluses in the appropriate column. Will this procedure yield the correct probability?
