Question
Show the conjecture is false by finding a counterexample. All prime numbers are odd.
Hint:
Use the property of prime numbers.
The correct answer is: Hence we disproved the conjecture
Complete step by step solution:
Prime numbers are the numbers that have only 2 factors, the number itself and 1.
‘ 2 ’ is a number that has its factors only as 2 and 1. So 2 is a prime number which is
not odd.
Hence we disproved the conjecture.
