A bag contains 15 balls. Exactly 3 of these balls are red. Alex reaches into the bag and randomly selects one of the balls. What is the probability that the ball that Alex selects is red?
(A) $\frac{1}{5}$
(B) $\frac{4}{5}$
(C) $\frac{1}{15}$
(D) $\frac{1}{4}$
(E) $\frac{14}{15}$
Since 3 of the 15 balls are red, then the probability that Alex randomly selects a red ball is $\frac{3}{15}$ or $\frac{1}{5}$.
