7+ (-5) = 2.
Therefor, 4^2 would be the right answer.
2x+3x -9. You can simplify this to 5x-9.
-0.25 would be -25/100 which can be reduced to -1/4
Answer:
There is a 1/8 chance.
If there are 4 cards in the deck, and one three card, it makes it a 1/4 chance of picking the card the first time.
The probability stays the second time you pull out a card.
So, you would do the equation 1/4 * 1/4, which is 1/8. That is the answer.
I think compound I have no idea
