QNOZ NO:2 (a) A (a) A random variable X is defined by the function: P(x)= xX Set up in tabular from the probablity distribution for for X. X1 (4-x) (/16) for x = 0,1,23,4​ set up, in tabular form the probability distribution for x​

The probability distribution for a discrete random variable X can be represented by a formula, a table, or a graph, which provides p(x) = P(X=x) for all x. The probability distribution for a discrete random variable assigns nonzero probabilities to only a countable number of distinct x values.

Answer 2

$\huge\frak\green{Probability}$

For example, if one asks for the probability of throwing a 7 on a standard pair of 6-sided dice, this "outcome" can occur in many ways: The first die can result in 1 and the second in 6, the first die 6 and the second 1, the first 5 and the second 2, and so on
