The produce manager at a farmer's market was interested in determining how many oranges a person buys when they buy oranges.  He asked the cashiers over a weekend to count how many oranges a person bought when they bought oranges and record this number for analysis at a later time.  The data is given below in the table.  The random variable x represents the number of oranges purchased and P(x) represents the probability that a customer will buy x apples. Determine the mean number of oranges purchased by a customer.

x	1	2	3	4	5	6	7	8	9	10
P(x)	0.05	0.19	0.20	0.25	0.12	0.10	0	0.08	0	0.01
