If 10% of the adult population are without debt at a particular time and a random sample of 20 people are chosen.
1. What is the probability distribution of the number of people WITHOUT DEBT?
2. What is the probability that NO MORE than 2 people are without debt?
3. What is the probability that at least 2 people are without debt?
4. How many people would be expected to be without debt?
