question 3

**Question 3** Suppose that a box contains 7 cameras and that 3 of them are defective. A sample of 2 cameras is selected at random. Define the random variable \( x \) as the number of defective cameras in the sample. Write the probability distribution for \( x \). | \( x \) | P(x) | |---------|------| | | | | | | | | | What is the expected value of \( x \)? [Here, the task is to fill in the table with the probability distribution values for \( x \), which represents the number of defective cameras in the sample. The table has columns for \( x \), the number of defective cameras, and P(x), the probability associated with each value of \( x \). The bottom of the section asks for the computation of the expected value of \( x \).]
