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.
