Please help, I have this problem and I don't know how to do it and I don't understand anything.

According to the National Center for Education Statistics, 66% of fourth-graders could read at a basic level in a recent year. Suppose that eight fourth-graders are randomly selected.

Find the probability that exactly five of them can read at a basic level.

Find the probability that more than six of them can read at a basic level.

The above data will pertain to a main topic of one of the following:

Discrete Probability Distributions (If so, in addition to answering word problem: find the mean, variance, and standard deviation. Explain and show work.),
Normal Distributions (If so, in addition to answering word problem: sketch and label the Normal Distribution Curve; sketch and label the standard normal curve; and compute the z-score. Explain and show work.),
Confidence Intervals (If so, in addition to answering word problem: determine the critical value by table or calculator. Explain and show work.),
Hypothesis Testing (If so, in addition to answering word problem: compute the test statistic. Explain and show work.), or
Correlation/Regression (If so, in addition to answering word problem: compute correlation coefficient. Explain and show work.)
