The following represents the probability distribution for the daily demand of microcomputers at a local store.
Demand Probability
0 0.1
1 0.2
2 0.3
3 0.2
4 0.2

The expected daily demand is _____.

Respuesta :

Answer:

The expected daily demand is =  2.2

Step-by-step explanation:

Given -

Demand  ( X  )                       Probability   P( X  )  

0                                                  0.1

1                                                   0.2

2                                                  0.3

3                                                   0.2

4                                                  0.2

Let X be the daily demand of microcomputers at a local store.

The expected daily demand is =

E( X  )  = [tex]\sum X \times P(X)[/tex]  

            =  [tex]0 \times 0.1 + 1 \times 0.2 + 2 \times 0.3 + 3 \times 0.2 + 4 \times 0.2[/tex]

             =  2.2
