Answer:
i. 
ii. 
Step-by-step explanation:
For each answer, there are only two possible outcomes. Either it is correct, or it is not. The probability of an answer being correct is independent of other answers. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:

The standard deviation of the binomial distribution is:

In this problem, we have that:
Each question has four options, one of which is correct. So the probability of getting each answer correct is 
There are 13 questions, so 
i. The mean of the random variable X

ii. The standard deviation of the random variable X

Answer:
Fadil earns $60 for each tv sold.
Step-by-step explanation;
13 (30) = 390
390 is the cost of all the warranties.
Subtract 390 from 1,170 to find the fixed amount for 13 tvs.
1,170 - 390 = 780
Divide 780 by 13 to find the fixed amount per tv.
780 ÷ 13 = 60
