Final answer:
To calculate the probability of selecting two people from a given population, you need to know the total number of people in the population and the number of people you are selecting. The probability can be calculated using the formula: Probability = Number of ways to select two people / Total number of possible selections.
Step-by-step explanation:
To calculate the probability of selecting two people from a given population, you need to know the total number of people in the population and the number of people you are selecting. The probability can be calculated using the formula:
Probability = Number of ways to select two people / Total number of possible selections
For example, if you have a population of 100 people and you want to select two people, the probability would be:
Probability = 100C2 / 100C2 = (100 * 99) / (2 * 1) = 4950 / 2 = 2475
