Question

The number of surjections from
A = {1, 2, 3, ....,10}. onto
B = {a, b} is

Answer 1

Answer:

The number of possible surjection from A = {1,2,3,...n} to B = {1,2} (where n ≥ 2) is 62 , then n =

Each element in A can be mapped onto any of two elements of B Total possible functions are 2^n For the f^n's to be surjections , they shouldn't be mapped ...
