You might answer this in a couple of different ways. 11 is the "odd" one, as it is the only "odd" number, while 4, 12 and 18 are all "even".

no because 11 is an odd nummber and 12 is a even and a odd cant go in a even number
Lets find out.2 + 3 = 5 (Odd)4 + 7 = 11 (Odd)12 + 13 = 25 (Odd)So it appears that the sum of an even and odd number is an odd number.
If you know that 144 is 12 squared, it would make sense to try 11 and 13. And viola!
In probability questions, the word "or" means add. Assuming the numbers are 1-12, the prime numbers would be 1, 2, 3, 7, and 11. The odd numbers are 1, 3 , 5, 7, 9, and 11. You don't add duplicates when determining probability, so all your options for a prime number or an odd number are 1,2,3, 5, 7, 9, and 11. This means there are 7/12 that are prime or odd, or a probability of 0.5833.
No odd whole numbers have 12 as a factor. 1 and 3 are odd numbers that are factors of 12.
