Respuesta :

Answer:

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

Step-by-step 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.)
