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%

-3.396 = -3.4

-0.708 = -0.7

0.304 = 0.3

0.955 = 1

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
