A disc jockey at a school dance has equal numbers of country, rock, and pop
songs that she randomly selects from. She designs a simulation to estimate
the probability that the next three songs she plays are all country songs.
Which simulation design could she use to estimate the probability?

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14

Solve 2 - 3 cos x = 5 + 3 cos x for 0° ≤ x ≤ 180° a. 150° b. 30° c. 60° d. 120°
