A and B disjoint - P(A⋂B) = 0
A and B independent - P(A/B) = P(B/A)
2.
Find the odd one out of the following
\(\hat { i } +2\hat { j } +3\hat { k } \)
\(2\hat { i } +4\hat { j } +6\hat { k } \)
\(7\hat { i } +14\hat { j } +21\hat { k } \)
\(\hat { i } +3\hat { j } +2\hat { k } \)
3.

Reason (R) : cos is negative in the first and fourth quadrant only.
Both A and (R) are true and (R) is the correct explanation of (A)
Both A and R are true but (R) is not the correct explantion of A
A is true R is false
A is false R is true

\(-\frac { 2 }{ 3 } ,-\frac { 2 }{ 3 } ,\frac { 1 }{ 3 } \)
\(-\frac { 2 }{ 3 } ,-\frac { 2 }{ 3 } ,-\frac { 1 }{ 3 } \)
5.

\(\tan { \frac { \theta }{ 2 } } \)
\(-\tan { \frac { \theta }{ 2 } } \)
\(\cot { \frac { \theta }{ 2 } } \)
\(-\cot { \frac { \theta }{ 2 } } \)
7.

2nCn
(-1)n2nCn
(-1)n2nCn-1
(-1)n/2nCn/2
8.
The sum up to n terms of the series \(\frac { 1 }{ \sqrt { 1 } +\sqrt { 3 } } +\frac { 1 }{ \sqrt { 3 } +\sqrt { 5 } } +\frac { 1 }{ \sqrt { 5 } +\sqrt { 7 } } +\)....is
\(\sqrt { 2n+1 } \)
\(\frac { \sqrt { 2n+1 } }{ 2 } \)
\(\sqrt { 2n+1 } -1\)
\(\frac { \sqrt { 2n+1 } -1 }{ 2 } \)
9.
If \({ log }_{ \sqrt { x } }\) 0.25 = 4, then the value of x is
0.5
2.5
1.5
1.25
10.
If A = {1, 2, 3}, B = {1, 4, 6, 9} and R is a relation from A to B defined by "x is greater than y". The range of R is __________
{1, 4, 6, 9}
{4, 6, 9}
{1}
None of these

3.
(c)
A is true R is false
4.
(a)
\(\frac { 2 }{ 3 } ,\frac { 2 }{ 3 } ,-\frac { 1 }{ 3 } \)
5.
(c)
- cos (ex)
6.
(b)
\(-\tan { \frac { \theta }{ 2 } } \)
7.
(d)
(-1)n/2nCn/2
8.
\(\frac{1}{\sqrt{1}+\sqrt{3}} =\frac{1}{\sqrt{3}+\sqrt{1}} \times \frac{\sqrt{3}-1}{\sqrt{3}-1}=\frac{\sqrt{3}-1}{2} \)
\(\frac{1}{\sqrt{3}+\sqrt{5}} =\frac{1}{\sqrt{5}+\sqrt{3}} \times \frac{\sqrt{5}-\sqrt{3}}{\sqrt{5}-\sqrt{3}} \)
\(=\frac{\sqrt{5}-\sqrt{3}}{2} \)
\(\text { Sum to } \mathrm{n} \text { terms }=\frac{(\sqrt{3}-1)}{2}+\frac{(\sqrt{5}-\sqrt{3})}{2}+\ldots . .\left(\frac{\sqrt{2 n+1}-\sqrt{2 n-1}}{2}\right)\)
\(=\frac{\sqrt{2 n+1}-1}{2}\)
9.
\(\log _{\sqrt{x}} 0.25 =4 \)
\((\sqrt{x})^{4} =0.25 \)
\((\sqrt{x})^{4} =\frac{1}{4} \)
\(x^{2} =\frac{1}{4} \)
\(\Rightarrow x=\frac{1}{2}=0.5\)
