Today was Art in the Park, an exhibition in display tents, of painting, jewelry, pottery and arts and crafts in our town's riverfront park. Plenty of people turned out. Lynn saw some friends but we didn't buy anything.
We like dark chocolate sea salt caramels. We went to Aldi's but they were out of the candy. So, we went to the main food store in town. As we entered, we were told that no cashier registers in the store were working and no credit card machines either. I tried to just give a ten dollar bill to a clerk but she said she could lose her job taking cash for the store's products with no way to get the money to the store itself. She said," I'm a single mother. I can't do anything that would get me fired." As we passed a bank of self-checking machines that had not been working, the young man who tended them tried once again to scan an item. It worked! Immediately, a line formed at that machine. We got our caramels. We have no idea what was wrong or why one self-check machine worked.
My friend asked me to be his back-up guy when he makes a presentation about the Monte Hall problem. It is a famous probability puzzler that stumped many people including probability specialists. I have a couple of blog posts about the problem which he will discuss on Thursday. If you are interested, Google the underlined words.
