Detemine k such that the following funciton is a p.m.f
`P(X=x)=k ((2^x)/(x!)), x=0,1,2,3 `
=0 otherwise .

Detemine k such that the following funciton is a p.d.f P(X=x)=k ((2^x)/(x!)), x=0,1,2,3 =0 otherwise .

Answer the following questions: For what value of k the following function would be a p.m.f.? f(x)={(k 1/2^x, "" , (x=0,1,2)),(0, "" , otherwise):} Also find the mean of the distribution.

If X is a r.v with pmf P(x)=kx,for x=1,2,3 ,=0,otherwise,then K=………..

Find k, if the following is p.d.f or r.v.f X. f(x) = {{:(kx^(2)(1-x), 0 lt x lt 1),(0, "otherwise"):}

Find k ,such that the function P(x)={{:(k({:(4),(x):}),,x=0","1","2","3","4,kgt0),(0,"otherwise."):} is a probability mass function (p.m.f.)

Find k ,such that the function P(x)={{:(k({:(4),(x):}),,x=0","1","2","3","4,kgt0),(0,"otherwise."):} is a probability mass function (p.m.f.)
