Answer:

The answer is "\frac{2}{15}" .

Explanation:

\to x = 0, 1, 2, 3, 4, 5\\\\\to p(x) \ for \ x  \ =   0, 1, 2, 3, 4, 5 = 0\\\\ \to c, 2c, 3c , 4c, 5c = 1\\\\\to 0 + c + 2c + 3c + 4c + 5c = 1\\\\\to 15c = 1\\\\\to c = \frac{1}{15}\\

\to p(x) \ for \ x  \ =   0, 1, 2, 3, 4, 5 = 0\\\\ \to \frac{1}{15}, \frac{2}{15}, \frac{3}{15}, \frac{4}{15}, \frac{5}{15}
