If A = {1, 2, 3}, B = {1, 2, 3, 4, 5}. the no. of functions from A to B such that f(i) ≤ ≤ f(j) when i is
Text Solution
Verified by ExpertsThe correct answer is:
C
f: A → → B such that f(i) ≤ ≤ f(j) when ever i ≤ ≤ j.
f(1) - No. of ways of selecting and arranging 3 elements
= 5 C 3 .1
f(2) - No. of ways of selecting and arranging 2 elements
= 2. 5 C 2
f(3) - No. of ways of selecting and arranging 1 element = 5 C 1 .
Total no. of ways = 
.
