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

• 26*25*10*9
• 9 years agoHelpfull: Yes(36) No(4)
• no.of alphabets=26 (a-z), no.of digits=10(0-9).
  ways of arranging two alphabets with out repetition=26*25;
  ways of forming two digits without repetition=10*9
  no.of combinations of forming the number on number plate= 26*25*10*9=58500

• two digits -> digits from 00 to 99. so 100 digits.
  two alphabets -> first alphabet may any of 26, second may any of 26.
  so totally, 26*26*100=67600 possbilities.

• 26P2 ways for selecting and arranging two alphabets without repetition i.e. 26 * 25
  10P9 ways for selecting and arranging two digits without repetition i.e. 10 * 9
  So total no. of combinations without repetition on the number plate is 26 * 25 * 10 * 9 = 58500

• options are:-
  a.58500
  b. 67600
  c. 65000
  d. 64320
  so answer is 26*25 * 10*9=58500

• we have - - - -
  let we go with alphabets totally 26 and we want to fill it with two alphabets, so 26c2
  now let go with number start from 0 to 9 totally 10 words, so 10c2
  and the total - - - -(Space is 4)
  
  so the final equation formed is 26c2*10c2*4 .
