Hi! I need help on how to correctly solve this problem (Pic. attached) Thanks!

In this coming election, 55% of Americans like to vote for a Democrat candidate for the next President of the United States. If we randomly select 20 Americans, find: a) The probability that exactly 14 of them like to vote for a Democrat president. (Round to four decimal places) b) The probability that no more than 12 of them like to vote for a Democrat president. (Round to four decimal places) c) The mean and standard deviation number of American people in this sample who like to vote for a Democrat President. Would it be unusual to have 16 people who like to vote for a Democrat President? (round the standard deviation to two decimal places) a. Would it be unusual? (Yes or No?)
