**For a prime number greater than 10 , the possible digits in 1's place:**

**=>Cannot be an even number or 0 (0,2,4,6,8)**

**=>Cannot be 5.**

**The possible numbers are**

**1 (eg.11)**

**3 (eg.13)**

**7 (eg.17)**

**9 (eg.19)**

1,3,5,7,9 at one's place but not(always.yeah but mostly)

...so why not (2,4,6,8,0) ? because they are even or most apparently they are divided by 2 which is breaking prime number's law.......and also 5 can not be there because then it would be divisible by 5
