When a die is thrown,the probability of getting an odd number less than $3$ is

$A$ bag contains slips numbered from $1$ to $100$. If Fatima chooses a slip at random from the bag,it will either be an odd number or an even number. Since this situation has only two possible outcomes,the probability of each is $\frac{1}{2}$. Justify.

Two dice are thrown together. Find the probability that the product of the numbers on the top of the dice is
$(i) \, 6$
$(ii) \, 12$
$(iii) \, 7$

$A$ die is numbered in such a way that its faces show the numbers $1, 2, 2, 3, 3, 6$. It is thrown two times and the total score in two throws is noted. Complete the following table which gives a few values of the total score on the two throws:

+	$1$	$2$	$2$	$3$	$3$	$6$
$1$	$2$	$3$	$3$	$4$	$4$	$7$
$2$	$3$	$4$	$4$	$5$	$5$	$8$
$2$	$3$	$4$	$4$	$5$	$5$	$8$
$3$	$4$	$5$	$5$	$6$	$6$	$9$
$3$	$4$	$5$	$5$	$6$	$6$	$9$
$6$	$7$	$8$	$8$	$9$	$9$	$12$

What is the probability that the total score is
$(i)$ even?
$(ii)$ $6?$
$(iii)$ at least $6?$

Chits numbered from $1$ to $100$ are put in a box and a chit is drawn randomly from the box. The probability that the chit drawn bears a $2$-digit number is ............

$A$ child's game has $8$ triangles of which $3$ are blue and the rest are red,and $10$ squares of which $6$ are blue and the rest are red. One piece is lost at random. Find the probability that it is a
$(i)$ triangle
$(ii)$ square
$(iii)$ square of blue colour
$(iv)$ triangle of red colour
