If the range ot a random vaniabie `X` is `0,1,2,3,` at `P(X=K)=((K+1)/3^k)` a for `k>=0,` then a equals

The range of a random variable X is 1,2,3,..., and P(X=k)=(c^(k))/(k!) where k=1,2,3... .Find the value of P(0ltXlt3)

For a random variable X if P(X=k) = 4((k+1)/5^k)a , for k=0,1,2,…then a= _____

If the probability function of a random variable X is defined by P(X=k) = a((k+1)/(2^k)) for k= 0,1,2,3,4,5 then the probability that X takes a prime value is

If the probability of a random variable X is a given below : {:(X=x:,-2,-1,0,1,2,3),(P(X=x):,(1)/(2),k,(1)/(5),2k,(3)/(10),k):} Then the value of k, is :

A random variable X takes the values 0,1,2,3,..., with prbability PX(=x)=k(x+1)((1)/(5))^x , where k is a constant, then P(X=0) is.

If X is the a random variable with probability mass function P(x) = kx , for x = 1,2,3 = 0 , otherwise then k = ……..

The range of random variable X={1,2,3,....oo} and the probabilities are given by P(x=k)=(C^(k))/(|__k) . Then C=

If |[3,-1],[1,k]|=0 then k is equal to?

The probability distribution of a discrate random variable X is : {:(X=x, 1,2,3,4,5),(P(X=x),k,2k,3k,4k,5k):} Find P (X le 4).
