# A discrete mathematics problem by Archana Chowdhury

Discrete Mathematics Level pending

An ant starts to move from the $$a_{11}$$ element of a matrix of order $$4\times4$$. It can only move left-right and up-down direction and it wants to reach $$a_{44}$$ element. Then what is the probability that the ant will pass through the element $$a_{23}$$?
