              The values of the weight can be anything and there is no right or wrong answer to it. However, whether they are
              playing Cricket or Tambola will be determined by values that are chosen. This is the reason why everyone gets
              different decisions, even though the situation/conditions are the same for everyone.

              Scenario 1: In reality the ground is big, there are no food outlets around the place, we have the cricket kit and
              we do not have tambola so, we assign YES or NO to the factors. We can convert the YES to 1 and NO to 0, and for
              bias, we always take 1.

              Now, we calculate the weighted sum by adding the products of factor value(1 or 0) with the weight of factor &
              reducing the weight of bias and compare it with the threshold of 0.
              When we calculate, the output is 1.0, which is higher than the threshold, which happens to be 0. The result will be
              to play cricket in the big ground on a picnic.
