Maths Problem Banks issue customers with 4 digit Pin Code numbers however the PIN codes have to have a pair of repeated digits 0889 6647 but not 3453 or 4444 how many codes are there?
the repeated digits can lie in any of 3 positions:XXYZ,YXXZ, or YZXXTherefore, the number of different possible repeated digit combinations is 10×3=30 (there are 10 different possible digits).There are then 9 values left that Y could be, after the X's have their values, and 8 values left that Z could be, to ensure no unintended repeated numbers.This gives (10×3)×9×8=2160. There are therefore 2160 possible codes.
How many combination codes is there using 4 5 6 7?
Combination codes are actually permutations and notcombinations. The number of codes depends on how long (how many digits) the code is and that is not specified in the question. Also, the number of codes depends on whether or not the digits may be repeated - again, not specified in the question.There are 24 permutations that use each of the numbers once in a 4-digit code.There are infinitely many codes in which the numbers can be used repeatedly, each an infinite number of times!
