I did this my sophmore year in highschool and I'm trying to remember lol. But first you add all the marbles together. 1+4+3. its eight. and since the marble was put back in this makes it an independant event. i believe the answer would be 2/8 considering that there isnt enough numbers to follow through with the equation of (P(a or b)=P(a)xP(b) . P is the probability and a and b are the variabls that represent the events. You would plug in the numbers of the probabilities into the equation, if you think the question calls for it. sorry it may not have been a staright up answer.
2x^2-y
Plug in the values.
2(3)^2-(-2)
2(3)^2+2
Exponents first.
2*9+2
18+2
20
The answer is 20.
I hope this helps!

In this question we will be using Commutative Law of Addition which is as follows:
The Law that says you can swap numbers around and still get the same answer when you add.
a+b =b+a
where a and b are addends.
Using this law, we can clearly see that order of addends does not matter at all in addition.
Now adding -5+6, we get 6-5 which is equal to 1
Answer is 1
I think 375. Because he will stayed there for 5 days. The coast of room per night is 75 euro. 75×5=375. I hope it help you!
