Step-by-step explanation:

Hope you get the answer,please mark me brainliest.

Answer 2

Total numbers :-

1, 2, 3, 4, 5, 6, 7, 8 , 9, 10, 11, 12, 13

Cubes :-

${1}^{3} = 1$

${2}^{3} = 8$

${3}^{3} = 27$

Here the cubes are 1 and 8 only because these two numbers are between 1 to 13.

We know that,

$\sf \fbox \orange{\frac{Favorable \: number \: of \: outcomes}{Total \: number \: of \: outcomes}}$

$\sf \fbox \green{ = \frac{2}{13}}$

There will no cancelation in the fraction given.

∴ The probability of cubic when number is taken at random from 1 to 13 is $\sf \fbox{\frac{2}{13}}$.
