Exact answer as a fraction = 1/3

Approximate answer in decimal form = 0.333

Approximate answer as a percentage = 33.3%

=====================================================

Explanation:

Check out the attached image below. It shows the various dice sums that add to either 4, 5 or 6. We have 12 occurrences total out of 6*6 = 36 overall giving 12/36 = 1/3 as the probability. This is in fraction form. As a decimal, 1/3 = 0.333 approximately which covers over to 33.3%

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.

this is not the answer this is just a question. is this middle school math?
