In maths paper there is a question on "Match the column" in which column A contains 6 entries \& each entry of column A corresponds to exactly one of the 6 entries given in column B (and vice versa) written
\( \mathrm{P} \) randomly. 2 marks are awarded for each correct matching \& 1 mark is deducted from each incorrect matching. A student having no subjective knowledge decides to match all the 6 entries randomly. Find
\( \mathrm{W} \) the number of ways in which he can answer, to get atleast \( 25 \% \) marks in this question.
