If u have a new deck of shuffled cards what is the probability you will choose a black card?

50%

Step-by-step explanation:

There are 4 suits in a deck of cards, hears diamonds clubs and spades

2 are red and 2 are black

This means 1/2 of the cards are black and 1/2 are red

P (black) = black cards / total cards

               = 1/2

               = 50%

d 192

step-by-step explanation:

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
