As men and women​ age, their risk of death increases. There are also health issues that can greatly impair older​ citizens' abilities to participate in activities and travel. Assume you are planning a 60th high school reunion and are wondering how many of the older adults would be able to attend. If you know that 22 women and 18 men are still​ alive, and are told that exactly 8 of them will​ attend, what is the probability that you would have exactly four men and exactly four women​ attend?
