What is the probability that the arrow stops on a shaded region if a circular spinner is divided into six regions, four regions each have a central angle of x∘x^{\circ}, and the remaining regions have central angles of 20∘20^{\circ} and 140∘140^{\circ}?
Plain-text mathematical notation (without MathML)
What is the probability that the arrow stops on a shaded region if a circular spinner is divided into six regions, four regions each have a central angle of x^(∘), and the remaining regions have central angles of 20^(∘) and 140^(∘)?
Original LaTeX notation
What is the probability that the arrow stops on a shaded region if a circular spinner is divided into six regions, four regions each have a central angle of $x^{\circ}$, and the remaining regions have central angles of $20^{\circ}$ and $140^{\circ}$?
