Question

Xerxes, Regina, Murray, Norah, Stav, Zeke, Cam, and Georgia are invited to a dinner party. They arrive in a random order and all arrive at different times. What is the probability that Xeres arrives first?

Answer 1

Since all eight individuals arrive in a random order, and there are eight equally likely arrival positions for each of them, the probability that Xerxes arrives first is 1/8. This is because there's one favorable outcome (Xerxes arriving first) out of eight possible outcomes (one for each guest)

So, the probability that Xerxes arrives first is 1/8 or 12.5%.
