The probability distribution of a random variable X is given below: X  -5  -4 -3 -2 -1 0 1 2 3 4 5  P(X)  p  2p   3p   4p   5p   7p   8p   9p   10p   11p   12p  Then the value of p is:

$\frac{-1}{72}$ $\frac{-2}{72}$ $\frac{2}{72}$ $\frac{1}{72}$

$\frac{1}{72}$

The correct answer is Option (4) → $\frac{1}{72}$
