1.) Equal likely chance would be 50/50 for having a dog or a cat. There are 3 possibilities: one dog and one cat, 50%, two dogs, 25%, or two cats, 25%. Adding the probabilities of having two of the same pets would theoretically give you a 50% chance.
2.) If you used two coins to simulate the possible outcome of pets the family had, you would have two fair sided coins. Each coin would have one dog side and one cat side (or heads and tails, where you would assign each pet a side of the coin).
3.) You have to do the expirament on your own.
4.) Having three pets changes the probability to a 33.3% chance of having each pet. Using number one as an example, add the probabilities to get a 66.6% chance for having three of the same pets.
5.) You can change the simulation by using a 3-sided die.
Answer:
Step-by-step explanation:
#1:
division sign means that we flip the fraction
now we can multiply all the constants together and all variables
now we can combine all the parts
#2:
5x-9y=-65
10x-3y=20
Multiple the first equation by 2
10x-18y=-130
10x -3y=20
Then subtract the two equations to get rid of the x
21y=-150
Divide the -150 by 21
Y=-7.14
Plug the y into the original equation. (Either one)
5x-9(-7.14)=-65
5x-64.28=-65
Then add 64.28 to the -65
5x=-0.72
Divide by 5
X=-0.144
I hope this is right
