Pascal's Triangle

This week picture is Pascal's Triangle. It is a geometric arrangement of the binomial coefficients in a triangle. This is how the construction of the triangle works. On row 0, write only the number 1. Then, to construct the elements of following rows, add the number directly above and to the left with the number directly above and to the right to find the new value. For example, the first number in the first row is 0 + 1 = 1, whereas the numbers 1 and 3 in the third row are added to produce the number 4 in the fourth row. Pascal's Triangle shows up is in probability, where it can be used to find combination.
