First off, rewrite all of the fractions so that they have a common denominator. That's 2/12, 2/12, and 4/12. Adding these together, we get 8/12. That's the probability of getting an A, B, or C — but not a D. The chance of getting a D is represented by the remaining 4/12 — or 1/3.

TIn short, the chance of rolling D is exactly 1/3.

How do you solve (8^1)^0

lutik1710 [3]

Answer:

Step-by-step explanation:

When numbers are raised to an exponent/power, it means how many times you are multiplying the number by itself.

Follow BEDMAS order. (Brackets, exponents, division/multiplication, addition/subtraction).

Solve inside the brackets of (8^1)^0 first

(8^1)^0 8^1 is 8. (Any number ^1 is itself).

= 8^0 Any number to the power of 0 is 1.

= 1

You can also follow the exponent rule where: $(x^{a})^{b} = x^{a*b}$

(8^1)^0 = 8^(1*0) = 8^0 = 1

B.) Marua will spend 2 hours to read 100 pages of sociology which means she can only read 60 pages of economics.
Therefore, the opportunity cost of reading 100 pages of sociology is forfeiting 40 pages (2 hours) of economics.
