According to a poll, 56% of voters support funding a new community center. a surveyor randomly selects 75 voters and asks each voter if he or she is in favor of the center. if being in favor of the center is a success, what is the probability of a success for this binomial experiment?

The answer is 0.56 or 56%.
Since there are 56% of voters, it will be computed as 56/100 = 0.56

A binomial experiment is an experiment where you have a determined number of independent trials with only two results. It has the accompanying properties: The trial includes n repeated trials. Every trial can bring about only two likely results. We call one of these results a success and the other, a failure. The possibility of success, meant by p, is the same on each trial.

The answer is c. 0.56. 

The mode of the numbers is 29.
