### Q: Why did the professor choose to lecture on the topic of lottery winning maths?

The professor enjoys exploring where mathematical ideas intersect with everyday life, and the lottery is a recreational activity that many people participate in. The lecture series aims to make math and money an entertaining theme.

### Q: How does probability play a role in understanding the lottery?

Probability is all about assessing the likelihood of certain events occurring. In the case of the lottery, probability helps determine the odds of winning and can also be used to make predictions about future events, such as the chance of rain.

### Q: What is the gambler's fallacy?

The gambler's fallacy is the belief that previous outcomes of a random event, such as a coin toss or lottery numbers, can influence future outcomes. In reality, each event is independent and unaffected by past outcomes.

### Q: Why do people tend to avoid using numbers that have won the lottery before?

This behavior stems from a misunderstanding of probability and the belief that numbers are less likely to come up again. Humans have memories and try to spot patterns, but lottery balls have no memory and each draw is an independent event.
