Like human viruses, computer viruses come in different forms and can affect your computer in many ways. Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation. Assume that you have 60 computers in your laboratory. Some of these computers are infected with either \( \text { Boot Virus, Companion Virus, or Macro Virus}\). When you select any 41 computers, there will be always different computers infected with these three type of viruses. How many \( \text {Companion Viruses, Boot Virus, or Macro Virus}\)could be in the laboratory?

Report your answer as the number of the computers infected with \( \text{Boot Virus }\)?
