3. A customer service rep has determined that the probability a customer call will result in a with a positive interaction 60% of the time and be contentious 40% of the time. Assume that each call is independent of the others. The rep is interested in determining how likely it is to receive various numbers of non- contentious calls during a standard day which contains 7 calls. , Define a random variable for this problem and state its distribution and parameters. Find the probability that there are 3 calls which are non-contentious. Find the probability that at least 2 calls which result in positive interactions. Find the probability that there will be 5 calls which are contentious. Find the probability that there are at least 4 calls which are contentious. a)
