I assume r.v. means random variable
So we have
And
The probability distribution will be as follows:
And that's the probability distribution for X.
A drawer contains 8 brown socks and 4 blue socks. A sock is taken from the drawer at random, its color is noted and it is then replace. This procedure is performed twice more. If X is the r.v "the # of brown socks taken", find the prob distribution for X
Can somebody explain this question to me pls!tnX
