Please answer my question.
And also give correct explaination. Please ​

Answer 1

Answer:

Number of distinct alphabets in the word EQUATION is 8

Number of 4 letter words that can be formed with repetition =8×8×8×8=4096

Number of 4 letter words that can be formed without repetition =8×7×6×5=1680

Number of 4 letter words that can be formed with atleast one repetition = (Number of 4 letter words that can be formed with repetition)-(Number of 4 letter words that can be formed without repetition)

=4096−1680=2416
