When calculating the parallel cost, you assume that keys will be roughly evenly distributed among buckets. This is a powerful assumption that makes bucket sort more efficient. You should make the same assumption when calculating the serial cost.

Serially, if you evenly distribute n keys into p buckets, then selection sort each bucket, each selection sort takes O((n/p)²) time, for a total cost of Ts = O(n + n²/p).
