The probability distribution of a random variable X is given by :
Then the value of K is : |
$\frac{1}{12}$ $\frac{1}{11}$ $\frac{1}{10}$ $\frac{1}{9}$ |
$\frac{1}{11}$ |
The correct answer is Option (2) → $\frac{1}{11}$ The value of probability should be equal to 1. $⇒2k+k+3k+4k+k=1$ $⇒11k=1$ $⇒k=\frac{1}{11}$ |
