Answer 1

To accomplish the teacher's goal of displaying the names of 2 students selected at random from a group of 30 students, where any possible pair of students is equally likely to be selected, we can use the following algorithm:1. Create a list of all 30 students' names.2. Use a random number generator to select two unique indices from the list.3. Display the names of the students corresponding to those indices.This algorithm ensures that each possible pair of students has an equal probability of being selected.
