A stock has a 25% probability of increasing by $10 and a 75% probability of decreasing by $5. What is the stocks expected increase or decrease?

Please help me!!

The stocks expected decrease is of $1.25.

Step-by-step explanation:

To find the expected change, we multiply each change by it's probability.

We have that:

There is a 25% probability of increasing by $10.

There is a 75% probability of decreasing by $5(that is, 75% probability of the value being -5).

What is the stocks expected increase or decrease?

0.25*10 - 0.75*5 = -1.25

Negative, so a decrease.

The stocks expected decrease is of $1.25.

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
