Question
Basic Math
A teacher has 25 students, and he wants to select two students for a pop quiz. To randomly select these two students, the teacher uses his calculator to generate a random number from the list (1,2,3..., 25), and then call the student that corresponds to that number in his roster. Then, the teacher repeats that procedure to select a second student. Hint: Since the teacher generates a random number from the list (1,2,3...,25) the second time as well, the number of the first student may be generated again. You may see this as two events with replacement. Johnny, is worried about being chosen twice. What is the probability that Johnny is called twice? 1/6251/6001/251/24
