Subject identification numbers in a certain scientific research project consist of five digits followed by four letters and

of five may occur also in the last group of three. How many distinct identification numbers are possible?
chosen from the letters A to Z
26PA
Evaluate 26P4
26!
26P4=
(26 -4)!
358,800
Since there are to be three digits in the third group, set up the permutation Notice that 3 digits are to be chosen
from the digits 0 to 9.
10P3
Evaluate 10P3
