According to one poll, 54% of households in a certain region had no landline and only had cell phone service. Suppose a random sample of 50 households from the region is taken. Complete parts (a) through (d) below. a. Find the probability that exactly 25 of the households sampled only have cell phone service. The probability that exactly 25 only have cell phone service is 0.096. (Type an integer or a decimal. Round to three decimal places as needed.) b. Find the probability that fewer than 25 households only have cell phone service. The probability that fewer than 25 only have cell phone service is (Type an integer or a decimal. Round to three decimal places as needed.)
