An Organization will give a prize to a local artist. The artist will be randomly chosen for among 3 painters, 7 sculptors, and 12 photographers. What is the probability that the artist chosen will be a painter or a sculptor?

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

the answer is b

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
