You select a card from a standard shuffled deck of 52 cards. Without replacing, you select another card. Find the probability th

Angelina_Jolie [31]

In a standard shuffled deck of 52 cards, half of the cards are black and half of the cards are red: (26 black cards, 26 red cards).

Since we are interested in pulling a black card first, the probability is 26/52.

Without replacing the card we have chosen, we are left with 51 total cards in the entire deck (25 black cards, 26 red cards).

Now that we want to pull a red card, we know that the probability will be 26/51.

Since we are interested in both events occurring simultaneously, we must multiply the probability of the first by the probability of the second, aka: (26/52) * (26/51)

The answer we are given is 0.2549

I have to write the linear process... of all of them.

Karo-lina-s [1.5K]

15−2x−8−3x=−x−12+4x+43

now combine all the like terms on each side.

Add -2x and -3x

subtract 15 and -8....you subtract because the sign are different

now do the same for the other side

−5x+7=−x−12+4x+43

−5x+7=3x+31

bring the x value from the right side to the left side.

−5x+7−3x=31

combine like terms on left side

−8x+7=31

now move +7 to the right side which become..

−8x=−7+31

−8x=24

we will need to single out X by dividing

$- \frac{8x}{ - 8} = \frac{24}{ - 8} = - 3$

answer: X= -3
