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

### Instruction:
Percius has a collection of marbles. 40% of them are clear. 20% are black, and the remainder are all the other colors. A friend of his asks if he can take five marbles. On average, how many marbles of other colors will his friend end up getting?

### Response:
 40% ของลูกบอลเป็นสีอื่น ๆ เพราะ 100 - 20 = <<100-20=80>>80
เพื่อนของเขาโดยเฉลี่ยจะได้ลูกบอลสีอื่น ๆ 2 ลูกเพราะ 5 x .4 = <<5*.4=2>>2
