Answer:
30 ballots are possible
Step-by-step explanation:
In an election with 6 candidates for one office and 5 candidates for another office
If we select 1 candidate for one office , there are possibilities of selecting 5 candidates for another office
If we select 2nd candidate for one office , there are possibilities of selecting 5 candidates for another office
So to get number of different versions of ballots possible , multiply the candidates
6 times 5= 30
So 30 ballots are possible
