Here is the equations in standard form
Answer:
Step-by-step explanation:
Given that you and a friend play a game where you each toss a balanced coin.
If the upper faces on the coins are both tails, you win $1;
if the faces are both heads, you win $2;
if the coins do not match (one shows a head, the other a tail), you lose $1 (win (−$1)).
Let Y be the amount won
Then Y can take values as 1,2 and -1
The above is the probability distribution for Y.
We can see that
both lines intersects at origin
so, the solution is x=0 and y=0
now, we will check each options
option-A:
now, we can set them equal
and then we can solve for x
now, we can find y
so, solution is x=0 and y=0
so, this correct...........Answer
