Q1) What do you mean by "Probability"? Create a hypothetical contingency table of data by using grid of three rows and four columns (label = rows and columns as you see fit.  For instance, rows might be age, and columns might be income level).  Insert hypothetical values for each cell in table. Develop 4 probability questions by using table that you as the instructor of statistics might ask class of students for test in probability.

Assume 1.5% of antennas on new Nokia cell phones are imperfect. For random sample of 200 antennas, determine the probability that:

a) None of the antennas is defective

b) Three or more of the antennas are defective.
