Let X denotes the number of hours you study during a randomly selected schoold day. The probabildity X can take the value of x is given by
`P(X=x)={(0.1,ifx=0),(kx, if x=1or2),(k(5-x),if x=3or4'),(0,otherwise):}`
where k is some unknown constant
What is the probability that you study for
exactly two hours?

Let X denotes the number of hours you study during a randomly selected schoold day. The probabildity X can take the value of x is given by P(X=x)={(0.1,ifx=0),(kx, if x=1or2),(k(5-x),if x=3or4'),(0,otherwise):} where k is some unknown constant Find the value of k.

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=1or2),(k(5-x),,if,,x3or4),(0,,,,otherwise):} 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 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=1or2),(k(5-x),,if,,x3or4),(0,,,,otherwise):} Find the value of k.

The probability distribution of a random variable X is given as under: P(X=x)={(kx2, fo r (x=1,2,3,4)),(2kx, fo r(x=5,6,7)),(0, otherwise):} where k is a constan. Calculate E(3X^2)

The probability distribution of a random variable X is given as under: P(X=x)={(kx^2, fo r (x=1,2,3,4)),(2kx, fo r(x=5,6,7)),(0, otherwise):} where k is a constant. Calculate P(Xge4)

The random variable X has a probability distribution P(X) of the form P(X) = {{:(k, "if" X = 0),(2k, "if" X = 1),(3k, "if" X = 2),(0, "otherwise"):} with k being some positive constant. The P (X = 2) is

Let X be a discrete random variable whose probability distribution is defined as follows: P(X=x)={(k(x+1), fo r(x=1,2,3,4)),(2kx, fo r (x=5,6,7)),(0, otherwise):} where k is constant, Calculate the vlaue of k.
