explain randomforest Machine Learning algorithm like you are 5 years old !

Being an analyst working on statistical analysis, more often than none, there is almost always a need to "explain" how did you come up with the conclusion with the techniques applied? The most demanding part of all this is: " you must explain this like I am 5 years old." Oki, so let me try to explain one machine learning algorithm called "randomforest" for a classification problem that is recognised as a black-box algorithm! Let's get started with a metaphor that hopefully is as close to everyday life as possible... In a congress, say that there are 100 members in total, they need to vote to decide whether they are going to pass a new law or not.
