Serggg [28]

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):

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

$E(x) = 21834$
