After two six-sided dice are rolled, what is the probability that the dice faces add up to either a 4 or 6? 0.222
0.139
0.167
0.083

0.222

Step-by-step explanation:

out of 36 outcomes you have 8 possible outcomes for a '4' or '6':

1,5

5,1

3,3

2,4

4,2

2,2

1,3

3,1

8/36 = 2/9 = .2 repeating

it would be 6xy and -16xy.
