If 6 is placed at the right end of AB, so the number is AB6. 
the value of the three-digit number formed is 294 more than AB, means that if AB6 - 294 = AB <span>

</span>AB 6 
- 2 9 4 
AB <span>

</span>6 - 4 = B = 2 <span>

</span>If B = 2, then the tens digit is 2 - 9 (which can't be) so 12 - 9 = 3 = A <span>

</span>A = 3, and B = 2 <span>

</span><span>check: 326 - 294 = 32</span>

A three digit number is formed at random using the digits
kramer

Answer:

2/3, or 66.7%

Step-by-step explanation:

There are 2 options for the first digit (3 or 4).

After the first digit is selected, it cannot be repeated, so there are 2 options left for the second digit.

After the first two digits are selected, there is only 1 option for the third digit.

So there are 4 permutations greater than 300.

The total number of permutations is 3! = 6.

So the probability is 4/6 = 2/3.
