Questions

Fоr questiоns 21-23: In 2016, Grаmmy winner Adele perfоrmed in Phoenix, AZ.

I had to refresh or reload the website several times before the "Purchase Tickets" page would show up. Suppose that X is the number of times that you had to reload and would see an error before the ticket page shows up, and that with each reload, there's a 20% chance that you will see the ticket page instead of an error.
