In a survey of

1146

people,

843

people said they voted in a recent presidential election. Voting records show that

71%

of eligible voters actually did vote. Given that

of eligible voters actually did vote, (a) find the probability that among

1146

randomly selected voters, at least

843

actually did vote. (b) What do the results from part (a) suggest?
