how is this calculated?

Determine whether you can use the normal distribution to approximate the binomial distribution. If you can, use the normal distribution to approximate the indicated probabilities and sketch their graphs. If you cannot, explain why and use the binomial distribution to find the indicated probabilities. A survey of adults in a region found that 56% have encountered fraudulent charges on their credit cards. You randomly select 100 adults in the region. Complete parts (a) through (d) below. A Sketch the graph of the normal distribution with the indicated probability shaded. A. O B. O C. O D. H= 56 H =56 H = 56 The normal distribution cannot be used to approximate the binomial distribution. 30 80 73 39 80 73 39 80 73 (c) Find the probability that the number who have encountered fraudulent charges on their credit cards is fewer than 60. (Round to four decimal places as needed.)
