 Can you explain this Halloween riddle? 🧊 Do you know what Boolean logic is? ❓ It is used in computers. 💻 _________________________________________________________ There are two inputs - A and B, and one output . The inputs and the output can be only 0 or 1. There are possible 4 different input combinations : AB 00, 01, 10, and 11 .  Each input can result in either 0 or 1.  Therefore, there can be 16 different Boolean functions: 2*2*2*2 = 16
