An integer is randomly chosen from the list 10, 11, 12, 13, 14, 15, 16, 17, 18, 19. What is the probability that the chosen integer is even?
(A) $\frac{3}{10}$
(B) $\frac{4}{10}$
(C) $\frac{5}{10}$
(D) $\frac{6}{10}$
(E) $\frac{7}{10}$
The number of integers in the list is 10 . Of these integers, 5 are even (they are 10, 12, 14, 16, and 18). Thus, the probability that the chosen integer is even is $\frac{5}{10}$.
