Let X denote the number of hours you study during a randomly selected school day.The probability that X can take the values of .x, has the following form, where K is some cons"tan"t.

Let X denote the number of hours you study during a randomly selected school day. The probability that X can take the values x, has the following form, where k is some unknown constant. P(X=x)={{:(0.1, "if "x =0),(kx, "if "x = 1 or 2 ),(k(5-x), "if " x=3 or 4),(0,"otherwise"):} (a) Find the value of k. (b) What is the probability that you study at least two hours ? Exactly two hours? At most two hours?

Let X denote the number of hours you study during randomly selected school day to probability that X can take the values of x, has the following form. P(X=x) = {{:(0.1, If x=0),(kx, if x=1 or 2),(k(5-x), if x =3 or 4),(0, " otherwise "):} find the value of k

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.

The random variable X has a probability distribution P(X) of the following form, where K is some number P(X)={{:(,K,"if x =0"),(,2K,"if x=1 "),(,3K,"if x=2 "),(,0,"otherwise"):} (a) Determine the value of K. (b) Find P(X lt 2) .

The value of lim_(x rarr k^(-)) x -[x] , where k is an integer, is

The random variable X has probability distribution P(X) of the following form. P(X)= {(k, if X=0),(2k,if X=1),(3k, if X=2),(0, "otherwise"):} Find P(X lt 2)

The number of integral values of K the inequality |(x^2+kx+1)/(x^2+x+1)|<3 is satisfied for all real values of x is....
