To Find:

we have to find the number  2 digit numbers can you make using the digits?

Step-by-step explanation:

• We have given numbers 1,2,3,4.
• For making two-digit number without the repetition of numbers we have two space first and second which are unit place and ten place.
• In the first place or unit place we have four options of number which are 1,2,3,4 we can put any one of them
• In the second place, we have three options because if one number is already assigned at unit place we cant put that number of ten place hence a total of three options.

• Hence, the total number formed will be $3\times4$

Hence, the total 2 digits number are 12.
