Are your finances, buying habits, medical records, and phone calls really private? A real concern for many adults is that computers and the Internet are reducing privacy. A survey conducted by Peter D. Hart Research Associates for the Shell Poll was reported in USA Today. According to the survey, 37% of adults are concerned that employers are monitoring phone calls. Use the binomial distribution formula to calculate the probability that:

a. Out of 5 adults, none is concerned that employers are monitoring phone calls.

b. Out of 5 adults, all are concerned that employers are monitoring phone calls.

c. Out of 5 adults, exactly 3 are concerned that employers are monitoring phone calls.
