Question 1197347: Suppose that a box contains 7 cameras and that 5 of them are defective. A sample of 2 cameras is selected at random, with replacement. Define the random variable
X as the number of defective cameras in the sample.
Write the probability distribution for X.
(Here there is a table on the left side it says 'k' and on the right side it says 'P(X=k)'.) There are three values on each side: on the left side there is '0,1,2' and on the right side there are 3 blank spots. Please find P(x=k).

What is the expected value of X?
