20 - 8.57 = 11.43.
0.63x12= 7.5 so the answer is 7.5
Solution: Telemarketing. the probability that a call will reach a live person is 0.2. the calls are independent. (a) a telemarketer places 5 calls. what is the probability that none of them reaches a live person.
Answer: The given random experiment can be considered as binomial experiment with probability of success = 0.2 and number of trials = 5
Therefore, we have:

Let x be the number calls that reach to live person.
We have to find 
Using the binomial probability distribution, we have:



Therefore, the probability that none of them reaches a live person is 0.3277
1 pound is 16 ounces so 1:16 maybe?
