Answer 2

Answer:

Step-by-step explanation:

we begin with basic definitions.

A composite number = A number formed by multiplying other whole numbers

Example : 6 can be formed by multiplying 3 by 2.

An odd number is a number not divisible by 2.

A number is divisible by 3 if it is 3 or a multiple of 3.

We need numbers that are:

1) Odd

2) Divisible by 3

3) Composite numbers

Between 1 and 20.

The numbers are :

9, 15

We only have these two numbers.

The probability of getting an odd, natural composite number that is divisible by 3 is :

3/20
