There are 75 students in a classroom. Each student has a laptop and a cell phone connected to the laptop. The cell phone can be either one of the following states: "Power On and Screen On", "Power On and Screen Off", and "Power Off". The laptop will be either on or off. Since the cell phone is connected to the laptop, the cell phone won't be power off when the laptop is on.

How many states, represented by all possible states of all cell phones and laptops, does this classroom have?
