Concept explainers
Lottery (S). The lottery in an extremely small state consists of picking two different numbers from 1 to 10. Ten Ping-Pong balls numbered 1 through 10 are dropped in a fish bowl, and two are selected. Suppose you bet on 2 and 9. What is the probability that you match at least one number? What is the probability you match both numbers?
