The probability distribution of a random variable X is given below:
| X | 0 | 1 | 2 | 3 |
| P(X) | k | $\frac{k}{2}$ | $\frac{k}{4}$ | $\frac{k}{8}$ |
Then value of $P(X≤ 2)+ P(X > 2)$ is
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 1
$P(X≤ 2)+ P(X > 2)$ = Probability Distribution of all random variables
$=1$
