Before answering the probability related questions, let us look at what the terms involved in the question mean:

Prime Numbers: A number which has only 2 factors,I.e. 1 and the number itself. Examples: 5,11,23,29, etc.

Composite Numbers: A number which has more than 2 factors. It can be expressed as a product of prime numbers. Examples: 20[2²*5],10[2*5],6[2*3], etc.

Odd Numbers: A number which is not a multiple of 2. Examples: 1,11,21, etc.

Even Numbers: Every multiple of 2. Examples: 22,2,212, etc.

Now, let's answer the given questions by applying the formula given below:

1. 6/16 = 3/8.

2. 8/16 = 1/2.

3. 8/16 = 1/2.

4. 9/16.
