The number of ways when the choice is not relevant is 10
How to determine the number of ways?
The number of objects are:
Object, n = 5
The object to choose are:
r = 3
Relevant choice
When the choice is relevant, we have:
[tex]Ways = ^nP_r[/tex]
This gives
[tex]Ways = ^{5}P_3[/tex]
Evaluate
Ways = 60
Hence, the number of ways when the choice is relevant is 60
Not relevant choice
When the choice is not relevant, we have:
[tex]Ways = ^nC_r[/tex]
This gives
[tex]Ways = ^{5}C_3[/tex]
Evaluate
Ways = 10
Hence, the number of ways when the choice is not relevant is 10
