Solution

Step $1$ : Definition of Prime and composite numbers.
The numbers which have only two factors, namely $1$ and the number itself are called prime numbers.
The numbers which have more than two factors are called composite numbers.
Step $2 :$ Finding prime and composite numbers from the list.
The given numbers are $50, 51, 52, 53, 54, 57, 59, 61, 63, 65, 67, 68, 69, 70, 71$
Therefore,
Prime Numbers: $53, 59, 61, 67, 71, 73$
Composite Numbers: $50, 51, 52, 54, 57, 63, 65, 68, 69, 70 .$
