Question

A local bakery has determined a probability distribution for the number of cheesecakes that they sell in a given day. The distribution is as follows:

Numbers sold in a day	0	5	10	15	20
Prob (Numbers Sold)	0.17	0.16	0.1	0.06	0.51

Find the number of cheesecakes that this local bakery expects to sell in a day.(Show work)

Answer 1

From the given data, the following Table is calculated:

Numbers sold in a day (x)	Prob (Numbers Sold) (p)	x p
0	0.17	0 X 0.17 = 0
5	0.16	5 X 0.16 = 0.80
10	0.10	10 X 0.10 = 1.00
15	0.06	15 X 0.06 = 0.90
20	0.51	20 X 0.51 = 10.20
Total =		12.90

So,

the number of cheesecakes that this local bakery expects to sell in a day =

                = 13 (Round to integer)

So,

Answer is:

13
