Talja [164]3 years ago

Answer:

7020

Step-by-step explanation:

The letter could be any 1 of the 26 and it could be placed in any 1 of 3 places so this makes 26*3 = 78 possibilities.

For each of these  there is any one of  permutations of 2 digits from 10

= 10P2 = 10! / 8! = 10*9 = 90.

So the answer is 78 * 90 =  7020.

Note I am assuming that the 2 digits picked are different - no duplicates.

please mark me brainliest!
