  1. Answer:

    The probability that in a sample of 400 registered voters at least 290 voted in their most recent local elections is:

    = 72.5%

    Step-by-step explanation:

    Sample of registered voters = 400

    Sample of voters that actually voted = 290

    Probability = 290/400 * 100

    = 72.5%

    b) This result above gives the statistic that for every 100 registered voters, 72.5 voters voted.  Probability measures the chance of an event occurring given other events.  Therefore, one can conclude that the voting was at least 72.5%.  Inversely, 27.5% of the registered voters did not participate or cast their ballots in the local elections.
