Hi I still need more help to this question please do not use chatgpt. BritBox is a streaming service that "brings you the best of British telly, direct from the UK" (https:/ /www.britbox.com/us/about). BritBox has shows in four genres: drama; mysteries; comedy; and documentaries/ lifestyle. To better understand the streaming market, an analytics team at BritBox collected data on which genres their customers watched.The analytics team found that: All customers watch at least one genre of shows. 80% of customers watch more than one genre of shows. 50% of customers watch mysteries. Of those who watch more than one genre of shows, 60% watch mysteries. Calculate the probability that a randomly selected customer watches exactly one genre of shows and that genre is not mysteries. This is my work Let's define the events: A = Customer watches exactly one genre of shows. B = Customer watches mysteries. We are asked to find the probability of P(A and not B), which means a customer watches…
