Construct truth table and identify if it’s tautology, contradiction, or contingency. (a) [(p V q) ∧ r] → [(p V r) ∧ (q V r)] (b) ((p → r) Ʌ (r → q)) → (q → p)
Give the correct answers. (Numbers 2 and 3 are the pictures shown) 1. Determine if the proporsotion (p→q) ↔ (q ∨ ¬p) is a tautology, contradiction or contingency.

This paper deals with Extended Huffman Codes. For instance, for a source emitting two symbols A and B, the second order extension involves coding messages AA, AB, BA and BB (2^2 in number). The third order extension involves messages such as AAA, AAB, etc. (2^3 in number). The probabilities of such strings are computed by multiplying the individual probabilities. Calculate third, fourth and fifth order extensions of a source message. 1. Choose an alphabet a set of at least six (6) symbols with assigned probabilities. It can be assigned as [ A=0.3; B= 0.7; C=0.1;D=0.2;E=0.5;F=0.15]. Compute the third, fourth and fifth order extension probabilities. Using the built-in algorithm, derive the Huffman Code for each extension. Compute the following quantities: (i) Average length of the codeword; (ii) The code efficiency; (iii) The Compression Ratio. Note: I am assuming but needs to be verified that if we need are using 6 symbols A to F. 6^3=216, the 6 to the third power comes…
