For teaching the concept of probability, Mrs. Verma decided to use two dice. Shet took a pair of die and write all the possible outcomes on the blackboard. All possible outcomes wave:

(1,1), (1,2), (1,3), (1,4), (1,5), (1,6)
(2,1), (2,2), (2,3), (2,4), (2,5), (2,6)
(3,1), (3,2), (3,3), (3,4), (3,5), (3,6)
(4,1), (4,2), (4,3), (4,4), (4,5), (4,6)
(5,1), (5,2), (5,3), (5,4), (5,5), (5,6)
(6,1), (6,2), (6,3), (6,4), (6,5), (6,6)
The probability that 6 will come up on both dice is

The probability that 5 will come up at least once is:

If $\left|\begin{array}{ccc}3& 1& -4\\ 3& 2& 5\\ 1& -1& 3\end{array}\right|=49$ then $\left|\begin{array}{ccc}6& 3& -16\\ 6& 6& 20\\ 2& -3& 12\end{array}\right|=$

The data for the conversion of compound A into its isomeride B are as follows :
$\begin{array}{ccccccccccccccccccc}\text{Time is hr :}& & & 0& & & 1& & & 2& & & 3& & & 4& & & \infty \\ \%\text{age of A :}& & & 49.3& & & 34.6& & & 25.8& & & 18.5& & & 13.8& & & 4.8\end{array}$
Show that this is a first order reaction.

Let $A=\left[\begin{array}{ccc}1& 1& 3\\ 5& 2& 6\\ -2& -1& -3\end{array}\right]$ . Find $tr\left(A^{2012}\right)$
