Hashing - General Questions

The keys 70, 24, 79, 86, 30 are inserted in this order into a hash table of size 13 using h(k) = k mod 13 and linear probing. At which index is 30 stored?

The keys 54, 91, 97, 92, 43 are inserted in this order into a hash table of size 13 using h(k) = k mod 13 and linear probing. At which index is 43 stored?

Primary clustering is a problem of:

The keys 14, 32, 11, 17, 57 are inserted in this order into a hash table of size 13 using h(k) = k mod 13 and linear probing. At which index is 57 stored?

The keys 15, 82, 62, 40, 16 are inserted in this order into a hash table of size 11 using h(k) = k mod 11 and linear probing. At which index is 16 stored?
