Answer:
Yes, she made an error. Caitlyn should have taken the desired outcomes, rolling a 3, 4, 5, or 6, and divided that by the total possible outcomes to get a probability of 4/6, or 2/3. She should have subtracted this probability from 1 to get the complement, which is 2/6, or 1/3.
Step-by-step explanation:
A
2 x 8+16 = 32 16 x 4 = 64
B
2 x 4 +8 = 16 8 x 8 = 64
C
4 x 8 + 32 = 64 2 x 32 = 64

Answer:
Simplified: 40
Step-by-step explanation:
To simplify this, we need to first separate the terms in this expression. There is a property of exponents that says: 
We can do this same thing to simplify this expression. Next, we can simplify each of these terms. 
simply becomes 4. In the other term, the 
simply cancel each other and leave the 10. This means that we're left with 4*10, which is 40
S+0.50m=7.50
2+0.50m=7.50
subtract from both sides
(2-2)+0.50m=7.50-2
0.50m=5.50
0.50m/0.50=5.50/0.50
divide 0.50 from both sides
m=11
