Determine if the method is fair. If it is not, how can it be adjusted to make it fair? A. The method is not fair. This can be resolved by finding the product of the outcomes of three spins instead of two.
B. The method is not fair. This can be resolved by using the sum of the two outcomes instead of the product.
C. The method is not fair. This can be resolved by using the same method with a spinner with only two same-sized sections instead of four.
D. The method is fair.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
