Question

A number plate can be formed with two alphabets followed by two digits, with no repetition. Then how many possible combinations can we get?

Answer 1

Answer:

PLS MARK ME

number of alphabate in english = 26.

Two position can be filled in 26*26 ways = 676 ways.

1st number position can be filled with (0 -9) = 10 ways.

2nd 1st number position can be in = 9 ways (repetition is not allowed, so ignoring the number used in 1st place)

Total number plate can be formed = 676*10*9 = 60840.

Answer 2

Answer:

58500

Step-by-step explanation:

first letter -> 26 ways

second letter -> 25 ways(since no repetition)

first digit -> 10 ways

second digit -> 9 ways (since no repetition)

then result will be 26*25*10*9=58500
