Write the probability that a number selected at random from the set of first 100 natural numbers is a cube.

Answer»

Let S = (1, 2, 3,………..,100)

Let A be the set of cubes from the set of first 100 natural numbers,

A = (1, 8, 27, 64)

P (selected no. being cube) = \(\cfrac{n(A)}{n(S)}\)

= \(\cfrac4{100}\)

= \(\cfrac1{100}\) = 0.04
