According to recent passport data, the percentage of people in a particular country who have a passport has risen dramatically. In 2007, only 27% of the country's citizens had a passport; in 2017 that percentage had risen to 45%. Assume that currently 45% of the citizens have a passport. Suppose 50 citizens of the country are selected at random. Complete parts (a) through (c) below. a. Find the probability that fewer than 22 have a passport. The probability that fewer than 22 have a passport is ☐ . (Type an integer or decimal. Round to three decimal places as needed.) b. Find the probability that at most 29 have a passport. The probability that at most 29 have a passport is (Type an integer or decimal. Round to three decimal places as needed.) c. Find the probability that at least 30 have a passport. The probability that at least 30 have a passport is ☐. (Type an integer or decimal. Round to three decimal places as needed.)
