Dell computer owners are very faithful. Despite reporting problems with their current systems, 90% of Dell owners said they would buy another computer from the company, based on the service they received. Suppose you randomly select three current Dell computer users and ask them whether they would buy another Dell computer system. Find the probability distribution for x, the number of Dell users in the sample of three who would buy another Dell computer.

a. p(0) = ______________

b. p(1) = ______________

c. p(2) = ______________

d. p(3) = ______________

e. What is the probability that exactly one of the three Dell computer users would buy another Dell computer?

______________

f. What is the probability that at least two of the three Dell computer users would buy another Dell computer?

______________ g. What are the population values for the random variable x?

Mean: ______________

Variance: ______________

Standard deviation: ______________
