Answer 1

Step-by-step explanation:

Let X be a discrete r.v. taking values 0,1,2,3,4 with probabilities k,2k,3k,4k,5k.then find value of k.

1/2

1/3

1/4

1/5

is 1/5

Answer 2

Answer:

The value of k for the discrete random varaiable is $\frac{1}{15}$

Step-by-step explanation:

• Discrete random variable is variable that can have only cerain points are not continous.

• Probability is the ratio of the favroable outcomes to the total outcomes.

• The total probability of the  variable or function is always one.
• The value of k is determined as follows.

       $k+2k+3k+4k+5k=1\\15k=1\\k=\frac{1}{15}$
