Intelligent Machines

Machines that use artificial intelligence to learn from the environment and past experiences to perform better in the presence of variability and uncertainty are called intelligent machines. Intelligence develops according to environment and experience. It is human-like behavior. When the computer system or any programmed machine learns from the inputs and corresponding outputs, it can be called an intelligent machine.

How do I answer this question?
Problem #6: Show that the following grammars are ambiguous by demonstrating two different parse trees and two different left-most derivations for the same terminal string in each case. Also for each case, find an equivalent unambiguous grammar: a) S-SS |a|b b) S-ABA A->aA | E B-bB c
Is the grammar LL(1)? Why or why not? If grammar is LL(1), use your parsing table to derive the string: modifier noun verb modifier

Hi there, Can anyone explain step by step how to answer to this question? I am aware what the answer is "none of the above", but I would like to see how to reach this answer step by step:
Calculate the hit and miss ratios in the cache and in the main memory for the processor assuming if the processor performs (n) number of total memory references over a period of time. Out of which (m) references are hits in the cache and (K) references of which are hits in the main memory. Also, provide your own reflection when cache (hit and miss) and memory (hit and miss) occur. Note: use own values for n, m, and K.
