Brainlet here.
If a key has 50% chance of opening a chest that has a key in it and that key in the chest has 50% chance of opening the second chest. What is the chance of opening the second chest?
Also if a study says that 1 out of ten people is homosexual. What are the chances that a group of ten men has a gay man?

And say how you solved both. Thanks.
