Q.1 Differentiate x
sinx w.r .t.x
Answer:-
Q.2 Prove that the set Z4 = {0, 1, 2, 3} is an abelian group w.r.t. addition modulo 4.
Answer:- abelian group:- In abstract algebra, an abelian group, also called a commutative group, is a
group in which the result of applying the group operation to two group elements does not depend on
their order (the axiom of commutativity). Abelian groups generalize the arithmetic of addition of
integers. They are named after Niels Henrik Abel.
Q.4 One third of the students in a class are girls and the rest are boys. The probability that a girl gets a
first class is 0.4 and that of a boy is 0.3. If a student having first class is selected, find the probability
that the student is a girl.

2. Answer:-
Q.6 The mean and standard deviation of 63 children on an average test are respectively 27.6 and 7.1.
To them are added a new group of 26 who have less training and whose mean is 19.2 and standard
deviation is 6.2. How will the value of combined group differ from those of the original 63 children as
to mean and standard deviation?
