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:
1/6
Step-by-step explanation:
We can make a Punnett square to find number of favourable outcome
so

The probability of rolling doubles given that the sum is 6
<h3> favourable outcome / number of outcome</h3>
6 / 36
1 / 6
The one to the right is the hundredth place
