Each of the 20 people has 19 other people to communicate to. If you add that all up you get 20*19 paths, but then each path is counted twice (back and forth), so we divide this by 2. 20*19/2 = 190.
The general forumula is n(n-1)/2
Answer:
Huffman code is use for encoding the language. The entropy when calculated is 1.5.
Explanation:
Using Huffman Coding scheme to encode:
The huffman coding scheme is described in the attachment.
To find entropy; we use the formula given below:
H = ∑
where H = Entropy and p = probability
p(A) = 50% = 1/2
p(B) = 25% = 1/4
p(C) = 25% = 1/4
