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
`rArr" "p+2p+3p+4p+5p+7p+8p+9p+10p+11p+12p=1`
`rArr" "72p=1rArrp=1/(72)`
