1. 2*3*3 = 18 different combinations.
2. P(3 or even) = P(3) + P(even)
1/6 + 3/6 = 4/6 = 2/3
3. Rolling an odd or even number on a number cube.
(8 + √11)(8 - √11)
8^2 - √11^2
64 - √11^2

Answer:
B) 0.4 (6 - 2w)
Step-by-step explanation:
You can only add or subtract with the numbers that have the same variable:
You can only add -2.2w and 1.4w
Which is -0.8w
Then add 4.8 and -2.4
Which is 2.4
Now the equation is -0.8w+2.4 or 2.4-0.8w
0.4 times 6 is 2.4
0.4 times 2w is -0.8w
Which is the same
-0.8w+2.4 or 2.4-0.8w
Hope this helps!
