The problem you shared reads:

"Diketahui 10 potong kertas diberi tulisan angka 1 sampai 10. Jika 2 potong kertas diambil lalu angka-angka pada potongan kertas tersebut dijumlahkan, peluang terambil potongan kertas dengan jumlah angkanya ganjil adalah ..."

### Translation:
"Given 10 pieces of paper numbered from 1 to 10, if 2 pieces of paper are drawn and the numbers on these pieces of paper are added, what is the probability that the sum of the numbers is odd?"

### To solve this:

1. **Identify odd and even numbers**:
   - Odd numbers between 1 and 10: {1, 3, 5, 7, 9} (5 numbers)
   - Even numbers between 1 and 10: {2, 4, 6, 8, 10} (5 numbers)

2. **Condition

Diketahui 10 potong kertas diberi tulisan angka 1 sampai 10. Jika 2 potong kertas diambil lalu angka-angka pada potongan kertas tersebut dijumlahkan, peluang terambil potongan kertas dengan jumlah angkanya ganjil adalah ...
