Answer:

E(x) = 21834

Step-by-step explanation:

Given

The above data

Required

Determine the expected value E(x)

E(x) is calculated as thus;

E(x) = \sum xf(x)

Where f(x) represents the total sale of each outcome;

For A:

f(x) = 295 *34

f(x) = 10030

For B:

f(x) =510 *49

f(x) =24990

For C:

f(x) = 790 *59

f(x) = 46610

Hence, E(x):

E(x) = 0.5 * 10030 + 0.30 * 24990 + 0.20 * 46610

E(x) = 21834

Mandarinka [93]
Add all the activities together

=3(x+2) + (8x-5) + 2x
multiply 3 by all in parentheses
=(3*x) + (3*2) + (8x-5) + 2x
=3x + 6 + 8x - 5 + 2x
combine like terms
=(3x + 8x + 2x) + (6 - 5)
=13x + 1
