Answer:
Probability distribution for x:
Step-by-step explanation:
We can model the number of defective sets in the group of TV sets (variable x) as a binomial variable, with sample size=3 and probability of success p=2/7≈0.2857.
The probability of k defective sets in the group is:
So, we have this probabilty distribution for x:
Answer:
