dari sejumlah pertandingan sepakbola, peluang suatu tim seri adalah 0,36 dan menang adalah 0,44. Jika dilakukan 80 kali pertandingan, tentukan frekuensi harapan tim tersebut kalah!
Answer (4)
To make it quickly we can consider only those numbers which will give us a decimal of xxx.7. There are only a few numbers like this: 85.2, 88.2, 20.5.
I tried adding 85.2 to 17.5 and it gave me 102.5 - it was close but not close enough :)
So I picked 85.2 + 20.5 = 105.7 and voila :)
The pair of numbers that sum up to 105.7 are 20.5 and 85.2 from the provided list. ;
The two numbers from the list that add up to 105.7 are 85.2 and 20.5. By systematically checking combinations, these numbers were confirmed to provide the correct sum. Therefore, 85.2 + 20.5 = 105.7.
