Answer:
<u>The probability that the first card is gray and the second card is pink= 5/78</u>
Step-by-step explanation:
A deck of cards has a 5 pink, 2 gray, And 6 black cards.
The total cards = 5 + 2 + 6 = 13
You pick two cards from the deck without replacement.
The probability that the first card is gray = 2/13
The remaining cards = 13 - 1 = 12
The probability that the second card is pink = 5/12
So,
The probability that the first card is gray and the second card is pink =
= 2/13 * 5/12 = 10/156 = 5/78
Answer:
x = 66
y = 68
Step-by-step explanation:
y is the same as the angle that is 68 degrees. Then, because the total of 46, x, and y should = 180, you solve for 180 by plugging in the y value.
46 + x + 68 = 180
114 + x = 180
x = 66
if you start at the point (0,1), you are going to go up and over to (-2,4), which means you will go up 3 and to the left, which means negative, 2
