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)`

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

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

The probability distribution of a random variable X is given below: X:0123P(X):k(k)/(2)(k)/(4)(k)/(4)(k)/(8) Determine the value of k Determine P(X 2) Find P(X 2)

If the probability distribution of a random variable X is given by X=x_(i):1234P(X=x_(i)):2k4k3kk Write the value of k

If a random variable "X" takes values ((-1)^(k)2^(k))/k, k=1,2,3,... with probabilities P(X=k)=(1)/(2^(k)) , then E(X)

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.
