The probability distribution of a random variable X is given as
Then, the value of p is

A

`1/72`

B

`3/73`

C

`5/72`

D

`1/74 `

Text Solution

Verified by Experts

The correct Answer is:
A
Sum of probabilities =1
` Rightarrow` p + 2P +3 P + 4 P + 5P + 7P +8p + 9p + 10p + 11p +12p =1
` Rightarrow ` 72 p =1
` Rightarrow p= 1/72`
