Answer:
At first, we have 3 expressions that are equal.
This is not true.
The expected value on playing this game is -5/36.
Given: 2 gold marbles, 9 silver marbles, and 24 black marbles.If it is gold, you win $3. If it is silver, you win $2. If it is black, you lose $1.
To find: Expected value on playing the game
Chance of occurrence of gold = 1/36
Chance of occurrence of silver = 9/36
Chance of occurrence of black = 26/36
On multiplying the given probability of occurence with the amount you would lose or win
we get,
1/36 * 3 + 9/36 * 2 - 26/36 * 1
3/36 + 18/36 - 26/36
=$ -5/36

Answer:
(-4,-3)
Step-by-step explanation:
-3x+3y = 3
2x-y =-5
Divide the first equation by 3
-x+y =1
Add this to the second equation
-x+y=1
2x-y =-5
---------------
x = -4
Now we need to find y
-x+y =1
-(-4) +y = 1
4+y = 1
Subtract 4 from each side
4-4 +y = 1-4
y =-3
(-4,-3)
