Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
On the island of Castor, there are 40 chess players. A quarter of the island's chess players have never lost to an AI. How many people on the island have lost to a computer, at least once?

### Response:
 Kati ya wachezaji 40 wa kawaida wa chess kwenye kisiwa hicho, robo yao hawajawahi kushindwa na kompyuta, maana yake watu 40/4 = <<40/4=10>>10 hawajawahi kushindwa na kompyuta.
Idadi ya watu kwenye kisiwa hicho ambao wameshindwa na kompyuta angalau mara moja ni 40-10 = <<40-10=30>>30.
