Estimating the mean of the discrete probability distribution

Reference no: EM1318727

An automotive center keeps tracks of customer complaints received each week. The probability distribution for complaints can be represented as a table or a graph, both shown below. The random variable xi represents the number of complaints, and p(xi) is the probability of receiving xi complaints.

xi	0	1	2	3	4	5	6
p(xi)	0.1	0.15	0.18	0.2	0.2	0.1	0.07

What is the average number of complaints received per week?

a) 2.12

b) 2.83

c) 3.32

d) 4.12
