Triangle PQR has coordinates P(-2, 1), Q(-2, 7), and R(1, 4). Triangle STU has coordinates S(-6, -2), T(6, -2), and U(0, -8). Use coordinate geometry to determine if these two triangles are similar. If they are not similar, state the reason

Suppose i pick a jelly bean at random from a box containing one red and eleven blue ones. i record the color and put the jelly bean back in the box. if i do this three times, what is the probability of getting a blue jelly bean each time? (round your answer to three decimal places.)
