The probability that a number selected at random from the set of numbers (1,2,3, , 100) is a cube, is

Options

  1. A1 25
  2. B2 25
  3. C3 25
  4. D4 25

Correct answer

A. 1 25

Step-by-step solution

n(S)=100 The set of cube numbers A= 1^3, 2^3, 3^3, 4^3 Total number in favour n(A)=4 Required probability = n(A) n(S) = 4 100 = 1 25
