C + (-8) + (-5) = 0
c - 8 - 5 = 0
c -13 = 0 (add 13 to each side)
<u> +13 +13 </u>
c = 13

The answer is D.

(-8) + (-5)= -13 so plug in -13 for variable c and you get -13+ -13= 0

The probability of pulling a blue marble and the coin landing tails up is 360/2500

<h3>How to determine the probability?</h3>

The tables of values are given as:

Color Times

Blue 18

Green 20

Yellow 12

Heads Tails

20 30

The probability of obtaining a blue marble is:

P(Blue) = 18/50

The probability of landing tails up is:

P(Tail) = 20/50

The required probability is:

P = P(Blue) * P(Tail)

This gives

P = 18/50 * 20/50

Evaluate the product

P = 360/2500

Hence, the probability of pulling a blue marble and the coin landing tails up is 360/2500
