Omer goes to the market and purchases some gum. There are 15 pieces of gum, including 7 mango pieces. What is the probability that a randomly selected piece of gum will be a mango flavored?

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.

idk
