The principal uses a computer to randomly select the name of a student from all the students in the school. With the computer program, it is possible to draw the name of the same student twice. If the principal selects the name of a student from the Acers on the first try, what is the probability she will draw the name of another student from the Acers on the second try?
There are a total of 400 students in the school, with 78 students in the Acers team.
After the first selection, there will be 399 students left in the school and 77 students left in the Acers team.
Therefore, the probability of drawing another student from the Acers team on the second try is 77/399, which simplifies to approximately 0.193 or 19.3%.
