Every prime number can be expressed in the form of 6n+1 or 6n-1 except 2 and 3.
But every number which can be represented in the form of 6n+1 or 6n-1 is not prime.
Example: 35 can be expressed as 6n-1 where n is 6 but its not a prime number.
Ceva’s theorem is a theorem about triangles in Euclidean plane geometry. Given a triangle ABC, let the lines AO, BO and CO be drawn from the vertices to a common point O (not on one of the sides of ABC), to meet opposite sides at D, E and F respectively. (The segments AD, BE, and CF are known as cevians.)
Online test 1 of #PROBABILITY can be attempted by clicking the link below. Active participation will motivate me to come up with such new projects. The solutions will be provided after one week. The report card will be generated once you complete the test. All the Best.
