Q: Identify pigeon and pigeonhole : Suppose that a computer science laboratory has 15 workstations and 10 servers. A cable can be used to directly connect a workstation to a server. For each server, only one direct connection to that server can be active at any ... to every server (using 150 connections), what is the minimum number of direct connections needed to achieve this goal? (ans 60)

Let f∘g denote function composition such that (f∘g)(x)=f(g(x)). Let f:A→B such that for all g:B→A and h:B→A we have f∘g=f∘h⇒g=h. Which of the following must be true? (ans : one to one) doubt: why it is not onto? Bcz : for function g , (to qualify to be a function, the entire domain of g must be mapped). So, domain of g= range of f.
