Can you give me the problem
Answer: The required probability is 0.004.
Step-by-step explanation:
Since we have given that
Number of pieces = 50
Number of defective pieces = 5
So, we need to draw 2 defective pieces.
So, the probability of drawing 2 defective pieces one after the other on the first and second samples would be

Hence, the required probability is 0.004.
