A recent study suggested that 70% of all eligible voters will vote in the next presidential election. Suppose 20 eligible voters were randomly selected from the population of all eligible voters. Use a binomial probability table to find:

a. The probability that more than 12 of the eligible voters sampled will vote in the next presidential election.

b. The probability that at most 12 of the eligible voters sampled will vote in the next presidential election.
