Question

The probability of having on add number between 5 and 15 is

Answer 1

Explanation:

First, we list down the numbers between 5 and 15: 6,7,8,9,10,11,12,13,14.

We can see that there are nine numbers in total and four of them are odd.

Hence, the probability of getting an odd number is

$\mathsf{\frac{Number\:of\:odd\:numbers}{Total\:number\:of\:numbers}}$

$\mathsf{ = \frac{4}{9} }$

Hence, the probability is 4/9.

Answer: 4/9
