A school is organizing a field trip to a museum. There are 30 students going on the trip, and they need to be divided into groups for the tour. The museum has a rule that each group must have at least 3 students but no more than 5 students. If the school wants to divide the students into as few groups as possible, how many groups will they have? The students can be divided in any way, as long as each group has between 3 and 5 students.

Solution
6 groups — To divide the students into as few groups as possible, we want to make the groups as large as possible. Since each group can have no more than 5 students, we start by dividing 30 by 5, which gives us 6 groups. However, 6 * 5 = 30, which means we can indeed divide the students into 6 groups of 5 students each. This is the minimum number of groups because if we try to make the groups any larger, we would have fewer than 3 students in some groups, which is not allowed. Therefore, the correct answer is 6 groups.

In an amusement park, there are three switches, but they are not labelled. Each switch corresponds to one of three light bulbs in a room. Each light bulb is either on or off. You can turn the switches on and off as many times as you want, but you can only enter the room one time to observe the bulbs. How can you figure out which switch controls which light bulb? You can try the switches in any order, but you must solve the problem in three steps or less. Which of the following strategies will work?
