This exam contains 16 pages (including this cover page) and 17 questions. The total
number of points is 142.
This is a custom exam written by Trevor, f
1.11. How many injective functions are there from cfw_1, 2, 3 to cfw_1, 2, 3, 4, 5?
Solution. Let f be such a function. Then f (1) can take 5 values, f (2)
can then take only 4 values and f (3) - only 3. Hence the total number of
functions is 5 4 3 = 60.
