-2x + 12 = 2y

6 = y + x -> x + y = 6

The answer is D.

A chef draws cookies randomly from a box containing 6 cookies of the same shape and size. There is 1 chocolate cookie, 3 almond

vovangra [49]

Answer:

1/5

Step-by-step explanation:

The probability of drawing an almond cookie the first time is 3/6=1/2, since there are a total of 6 cookies and 3 of them are almond. However, the second time the chance is 2/5, since there are 5 cookies left and only two of them are almond. The equation to model this is therefore:

$P=\dfrac{1}{2}\cdot \dfrac{2}{5}=\dfrac{1}{5}$

Hope this helps!
