1. The faces of a die bear the numbers 1,3,5,7,9, 11. The die is rolled. What is
the probability of event A of getting a perfect square number on the upper face of
the die? Complete the following activity.
Let S be the sample space of a die bear the numbers 1, 3, 5, 7, 9, 11.

(a) A is the event of getting a perfect square number.
.. A
n(A) =
P(A) = 3
2. The first term of an A.P. is 5 and the common difference is 4. Complete the
following activity to find the sum of first 12 terms of the A.P.
Here, first term a = Did=O, S12 = ?
Sn = 27/11
.S12 = ? [10+
: S12 = 6 [10+O)
.S12 = 6 x
:S12=0​
