Evaluate 5C3
5 answers
Is it 5C^3? Is 3 an exponent?
its like 5^C3....i posted it on wednesday and Reiny responded but never answered me back....
its the counting principle....
Do you mean combinations of five taken 3 at a time perhaps?
If so
C(n,r) = n!/[r!(n-r)! ]
= 5!/[3!2!]
=5*4/2!
=5*2
=10
If so
C(n,r) = n!/[r!(n-r)! ]
= 5!/[3!2!]
=5*4/2!
=5*2
=10
yes, thank you Damon...i couldn't figure how to explain it
