# The probability that a number selected at random from the set of numbers { 1,2,3,.....100} is a cube is

$\begin {array} {1 1} (A)\;\large\frac{1}{25} & \quad (B)\;\large\frac{2}{25} \\ (C)\;\large\frac{3}{25} & \quad (D)\;\large\frac{4}{25} \end {array}$

$n(S)=100$
$n(A)=n \{1^3,2^3,3^3,4^3 \}$
