Question

A local bakery has determined a probability distribution for the number of cheesecakes it sells in a given day. The distribution is as follows: Find the number of cheesecakes that this local bakery expects to sell in a day. 20 14.05 13.95 10

Answer 1

Number of cheesecakes local bakery expects to sell in a day = 14 (Approx.)

Explanation:

Given:

Number sold Probability xP(x)

0 0.1 0

5 0.19 0.95

10 0.05 0.5

15 0.14 2.1

20 0.52 10.4

Find:

Number of cheesecakes local bakery expects to sell in a day

Computation:

Number of cheesecakes local bakery expects to sell in a day = Sum of xP(x)

Number of cheesecakes local bakery expects to sell in a day = 0 + 0.95 + 0.5 + 2.1 + 10.4

Number of cheesecakes local bakery expects to sell in a day = 13.95

Number of cheesecakes local bakery expects to sell in a day = 14 (Approx.)
