Mathematics Standards for K-8 instruction (Billstein‚ Libeskind & Lott‚ 2010). This semester‚ which presented the second half the two-part course‚ the MTH/157 curriculum gave appropriate statistical methods to analysis data‚ applied basic concepts of probability‚ applied and identified geometric figures and shapes for problem solving‚ and identified applications of measurements. This class introduced very interesting‚ exciting

1 Introduction The N-Queens problem is a classical AI problem. Its name is derived from the allowed moves for the queen piece in chess. Queens are allowed to move horizontally‚ vertically‚ or diagonally‚ backward and forward‚ with the only restriction being that they can move in only one direction at a time. A queen that can reach another piece in one move captures it. The N-Queens problem is based on the notion of trying to place N queens on an N x N grid‚ such that no queen will be able to capture

Modelling Revision Mutually exclusive event- add the probabilities together to find the probability that one or other of the events will occur. E.g men/woman P(A or B)= P(A)+P(B) Non mutually exclusive- shared characteristic P (A or B)= P(A) + P(B) – P(B+A) Independent events – outcome is known to have no effect on another outcome P (A+B) = P(A) X P(B) Dependant events- outcome of one event affects the probability of the outcome of the other. Probability of the second event said to be dependent on the
