Tutoring probability, a better example than this might be hard to find. The tutor explains about the Las Vegas square in Careers® by Parker Brothers.
I explain expected value in my post from August 16, 2013, showing by example that the expected value of rolling a fair six-sided die is 3.5.
My younger son and I have played Careers® often at times. From early on, he has enjoyed the Las Vegas square. On that square, the player pays $3K, then gets back $1K multiplied by the roll of one die.
With the expected value of the roll being 3.5, the player is expected to receive $3500, so come out ahead by $500 each time, on average. I wonder if, intuitively, my son realized that soon after we started playing, when he would have been around 7 years old.
I don’t imagine Las Vegas in real life gives as promising odds as Las Vegas in Careers®.
