Determine whether you can use a 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 a binomial distribution to find the indicated probabilities. a survey of u. s. adults found that 64% watch nfl football. you randomly select 20 u. s. adults and ask them whether they watch nfl football. find the probability that the number who watch nfl football is
(a) exactly 10,
(b) less than 7, and
(c) at least 15, and
(d) identify any unusual events. explain.
determine whether a normal distribution can be used to approximate the binomial distribution.
