List of top Mathematics Questions on Probability Distribution asked in AP EAMCET

If the probability distribution of a random variable \( X \) is given as follows, then find \( k \):
probability distribution of a random variable X
An urn contains 3 black and 5 red balls. If 3 balls are drawn at random from the urn, the mean of the probability distribution of the number of red balls drawn is:
If \(6\) is the mean of a Poisson distribution, then
\[ P(X\geq3)= \]
The discrete random variables \(X\) and \(Y\) are independent from one another and are defined as
\[ X\sim B(16,0.25) \] and
\[ Y\sim P(2). \] Then the sum of the variances of \(X\) and \(Y\) is
