In a Bayesian network with n discrete random variables,
a) describe the structure and the contents of the conditional probability tables (CPT)
b) given an instance where the values of n – 1 of the variables are known, how would you go about determining the most likely value of the nth variable?

You download a PDF file from the Internet and upload it to VirusTotal in order to make sure that it is not malicious. The report from VirusTotal says that 1 out of 50 antivirus engines, namely Alibaba, identifies the file as a Trojan. Do you think that this is right? What would you recommend an appropriate course of action would be to solve this?
You are given an RSA crytosystem with primes of p=101, q=701 and a private exponent of d=23, what is the complete public key information that needs to be published? (20 marks)
Code generation for expressions.
Generate CMA code for the following expressions: a ← 2 • (c+ (b − 3)) b ← b • (a +3)
Assume the following address environment: ρ = {a→ 5, b→ 6, c→ 7}
Execute the generated code by displaying the stack contents after each instruction! Assume that the variables are initialized with the values a = 22, b = 33 and c = 44.
