Let A= x, y, z, u and B= a, b . A function f: A B is selected randomly. The probability that the function is an onto function is

Options

  1. A1 8
  2. B5 8
  3. C1 35
  4. D7 8

Correct answer

D. 7 8

Step-by-step solution

Total cases =2 2 2 2=16 We know that Probability of onto =1-( Probability of not onto) Probability = Number of favorable event Total event Probability of onto =1- 2 16 = 14 16 = 7 8
