Q. Akan di susun bilangan 33 angka berbeda dari angka angka 1,2,3,4,5,6,7,81,2,3,4,5,6,7,8. Banyak susunan yang mungkin bisa di bentuk apabila bilangan tersebut ganjil adalah.\newlineA. 180180\newlineB. 4646\newlineC. 126126\newlineD. 6464\newlineE. 9090
  1. Identify Odd Digits: For a number to be odd, the last digit must be odd. There are 44 odd digits available: 11, 33, 55, 77.
  2. Choose Last Digit: The last digit can be any of the 44 odd digits. Once the last digit is chosen, there are 77 options left for the first digit (since it can't be 00 and can't be the digit chosen for the last place).
  3. Select First Digit: After choosing the last and first digits, there are 66 options left for the middle digit.
  4. Determine Middle Digit: Multiply the number of options for each place to find the total number of possible numbers: 77 options for the first digit ×\times 66 options for the middle digit ×\times 44 options for the last digit.
  5. Calculate Total Combinations: Calculate the total number of combinations: 7×6×4=1687 \times 6 \times 4 = 168.
