Correct Answer - A
`(a)` Let us first distribute `4` left gloves to four person in `4!` ways.
If no one gets the corresponding right glove then no. of ways `=4!(1-(1)/(1!)+(1)/(2!)-(1)/(3!)+(1)/(4!))=9`
Then number of favourble ways `=9xx4!=216`
Total number of ways `4!xx4!`
`:.` Required propability `=(216)/(4!xx4!)=(216)/(576)=(3)/(8)`

If the pair of straight lines `ax^(2)-2pxy-y^(2)=0and x^(2)-2qxy-y^(2)=0` are such that each pair bisects the angle between the other pair , then prov

Combined equation of the bisectors of the angles between pair of lines `x^(2)-2pxy-y^(2)=0` is `(x^(2)-y^(2))/(1-(-1))=(xy)/(-p)` or `px^(2)+2xy-py^(2)=0` This must be same as the given equation of pair of bisectors i.e.,...

Suppose that 90% of people are right-handed. What is the probability that at most 6 of a random sample of 10 people are right-handed?

A person can be either right-handed or left-hended. It is given that `90%` of the people are right-handed. Therefore, `p=P("right-handed")=9/10` `q=P("left-handed")=1-9/10=1/10` Using binomial distribution, the probability that at most six...

m balls are distributed among a boys and b girls. Prove that the probability that odd numbers of balls are distributed to boys is `((b+a)^m - (b+a)^m)

Suppose than p and q, respectively, denote the probabilities that a thing goes to a man and a women. `p=(a)/(a+b)and q=(b)/(a+b)` Now, the probabilities of 0,1,2,3,… thing going to men...

`5` different objects are to be distributed among `3` persons such that no two persons get the same number of objects. Number of ways this can be done

Correct Answer - B `(b)` Division of objects can be `(0,1,4)` or `(0,2,3)` So total number of distribution ways `=(5!)/(0!*1!*4!)xx3!+(5!)/(0!*2!*3!)xx3!` `=30+60=90` ways

The probability of event `A` is `3//4`. The probability of event `B`, given that event `A` occurs is `1//4`. The probability of event `A`, given that

Correct Answer - C `(c )` `P(A)=(3)/(4)`, `P(B//A)=(1)/(4)` `P(A//B)=(2)/(3)` `P(B//A)=(P(BnnA))/(P(A))=(1)/(4)` (given) `:.P(BnnA)=(3)/(4)*(1)/(4)=(3)/(16)` Now `P(A//B)=(P(AnnB))/(P(B))=(2)/(3)`(given) `:.P(B)=(3)/(2)*(3)/(16)=(9)/(32)` `:. P(AuuB)=(3)/(4)+(9)/(32)-(3)/(16)=(24+9-6)/(32)=(27)/(32)` `:. P(A^(C )nnB^(C ))=1-P(AuuB)=1-(27)/(32)=(5)/(32)`

8. If \( A=\left[\begin{array}{ll}1 & 3 \\ 4 & 1\end{array}\right] \), then find \( \left|3 A^{\prime}\right| \).

Matrix A \(=\begin{bmatrix}1&3\\4&1\end{bmatrix}_{2\times2}\) |3 A'| = 2 \(A'=\begin{bmatrix}1&4\\3&1\end{bmatrix}_{2\times2}\) We know that ⇒ |K A| = (K)3 |A| ⇒ |3 A'| = 32 |A'| \(A'=\begin{bmatrix}1&4\\3&1\end{bmatrix}\) ⇒ |A'| = 1 x 1 - 4 x 3 ⇒ 1 - 12 = -11 ⇒...

In \( III ^{ rd } \) group of salt analysis for cations \( NH _{4} Cl \) and \( NH _{4} OH \) are added as group reagents. Which of the following can be used instead of \( NH _{4} Cl \) ? (a) \( NaCl \) (b) \( \left( NH _{4}\right)_{2} SO _{4} \) (c) \( \left( NH _{4}\right)_{2} C _{2} O _{4} \) (d) \( NH _{4} NO _{3} \)

d) NH4NO3 As it provides NH+4 ions which suppresses the ionisation of NH4OH so that only the group 3rd cations are precipitated as hydroxides because of their low solubility products and NO−3 ions...

9. (i) If \( A =\left[\begin{array}{rr}2 & -1 \\ -1 & 2\end{array}\right] \), verify \( A ^{2}-4 A +3 I = O \), where \( I =\left[\begin{array}{ll}1 & 0 \\ 0 & 1\end{array}\right] \) and \( O =\left[\begin{array}{ll}0 & 0 \\ 0 & 0\end{array}\right] . \) Hence find \( A ^{-1} \) (W.

4. The value of \( \left(\frac{1}{2}\right)^{-2}+\left(\frac{1}{3}\right)^{-2}+\left(\frac{1}{4}\right)^{-2} \) is (a) \( \frac{61}{144} \) (b) \( \frac{144}{61} \) (c) 29 (d) none of these

Correct answer is:- (c) 29 Explanation:-  1/2-2 + 1/3-2 + 1/4-2 = 22 + 32 + 42 (x-1 = 1/x) = 4 + 9 + 16  = 29
