A recent study suggested that 70% of all eligible voters will vote in the next presidential elections. Suppose 20 eligible voters were randomly selected from the population of all eligible voters. Use a binomial probability table to find the probability that more 10 but fewer than 16 of the 20 eligible voters sampled will vote in the next residential election.
The answer is 0.714 but I would like to see the workings.
