Answer:
You need 5 bits to encode al the 24 greek distinct lowercase letters.
Explanation:
o encode 24 greek distinct lowercase letters, you should be able to write in binary language 24 different combinations.
With 1 bit you have only 2 possible combinations. Not enough.
With 2 bit you have only 4 possible combinations. Not enough.
With 3 and 4 bit you have only 8 and 16 possible combinations. Not enough.
With 5 bit you have 32 possible combinations. This is enough to encode all the 24 Greek letters.
