We have the following given
p1 - probability for outcome 1
p2 - probability for outcome 2
p3 - probability for outcome 3
v1 - amount of money that you will win or lose for outcome 1
v2 - amount of money that you will win or lose for outcome 2
v3 - amount of money that you will win or lose for outcome 3
Therefore,
p1v1 + p2v2 + p3v3 is the average money you win or lose in playing the game.
First leave the first fraction alone.
Then turn the division sign into a multiplication sign.
Flip the second fraction over ( find its reciprocal ).
Multiply the numerators of the two fractions together. This result will be the numerator ( the top part ) of your answer.
Multiply the denominators of the two fractions together. The result will be the denominator ( the bottom part ) of your answer.
Then simplify your fraction by reducing it to the simplest terms.
It would be great if you added some more details, but for common denominators you try to find the least common number that the 2 or more of the numbers you got have!
For example:
1/2 and 2/3 if you multiply 2 by 3 and 3 by 2, they both are 6, so you would multiply 1/2 both by 3 to make it into 3/6 and 2/3 by 2 to make it into 4/6!
Answer:
1. -9xy
2. 6ab
3.-8mn
4. 17nx
Step-by-step explanation:
Because they are both even numbers
