Answers & Solutions:<\/strong><\/span><\/p>\n

1)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

Total number of oranges in the box = 12<\/p>\n

Number of ways of selecting 3 oranges out of 12 oranges, n(S) = $C^{12}_3$<\/p>\n

= $\\frac{12 \\times 11 \\times 10}{1 \\times 2 \\times 3} = 220$<\/p>\n

Number of oranges which became bad = $\\frac{12}{3}=4$<\/p>\n

Number of ways of selecting 3 oranges out of 4 bad oranges = $C^4_3 = C^4_1 = 4$<\/p>\n

Number of desired selection of oranges, n(E) = 220 – 4 = 216<\/p>\n

$\\therefore$ $P(E) = \\frac{n(E)}{n(S)}$<\/p>\n

= $\\frac{216}{220}= \\frac{54}{55}$<\/p>\n

=> Ans – (B)<\/p>\n

2)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Word = FOREHAND<\/p>\n

There are 2 pairs of letters\u00a0which have as many letters between them in the word as they have in the English alphabet<\/p>\n

FA and RN<\/p>\n

3)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Total balls in bag A = 4 + 6 = 10<\/p>\n

Probability that ball is green = $\\frac{4}{10}$<\/p>\n

Total balls in bag B = 3 + 4 = 7<\/p>\n

Probability that ball is green = $\\frac{3}{7}$<\/p>\n

=> Required probability = $\\frac{4}{10} \\times \\frac{3}{7}$<\/p>\n

= $\\frac{6}{35}$<\/p>\n

4)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

Total number of balls = 2 + 3 + 2 = 7<\/p>\n

Total number of outcomes = Drawing 2 balls out of 7<\/p>\n

= $C^7_2 = \\frac{7 \\times 6}{1 \\times 2} = 21$<\/p>\n

Favourable outcomes = Drawing 2 balls out of 5 (so that none is blue)<\/p>\n

=\u00a0$C^5_2 = \\frac{5 \\times 4}{1 \\times 2} = 10$<\/p>\n

=> Required probability = $\\frac{10}{21}$<\/p>\n

5)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Total number of balls in the bag = 8 + 4 + 5 = 17<\/p>\n

P(S) = Total possible outcomes<\/p>\n

= Selecting 5 balls at random out of 17<\/p>\n

=> $P(S) = C^{17}_5 = \\frac{17 \\times 16 \\times 15 \\times 14 \\times 13}{1 \\times 2 \\times 3 \\times 4 \\times 5}$<\/p>\n

= $6188$<\/p>\n

P(E) = Favorable outcomes<\/p>\n

= Selecting 2 brown, 1 orange and 2 black balls.<\/p>\n

=> $P(E) = C^8_2 \\times C^4_1 \\times C^5_2$<\/p>\n

= $\\frac{8 \\times 7}{1 \\times 2} \\times 4 \\times \\frac{5 \\times 4}{1 \\times 2}$<\/p>\n

= $28 \\times 4 \\times 10 = 1120$<\/p>\n

$\\therefore$ Required probability = $\\frac{P(E)}{P(S)}$<\/p>\n

= $\\frac{1120}{6188} = \\frac{280}{1547}$<\/p>\n

6)\u00a0Answer\u00a0(E)<\/strong><\/p>\n

The word ‘REPLACE’ has 2 E,1 A,1 R,1 C,1 L,1 P.
\nHence no. of ways in which it can be arranged=$\\frac{7!}{2!}$.
\n=$\\frac{5040}{2}$.
\n=$2520$.
\nHence, Option E is correct<\/p>\n

7)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

Out of the 16 eggs, 5 eggs are rotten and 11 eggs are in good condition.<\/p>\n

According to the question, out of the two eggs drawn one is rotten and the other is in good condition.<\/p>\n

Hence, required probability = $ \\frac{^5C_{1} * ^{11}C_{1}}{^{16}C_{2}} = \\frac{5*11}{16*15\/2} = \\frac{11}{24}$<\/p>\n

Hence, option A is the right choice.<\/p>\n

8)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

Number of non-yellow balls = 4 + 6 = 10
\nRequired Probability = $\\frac{^{10}C_2}{^{15}C_2} = \\frac{3}{7}$<\/p>\n

9)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

In order to solve this question, let us find the total number of ways of arranging four boys and two girls and remove the number of arrangements in which both the girls sit together.<\/p>\n

Total number of ways of arranging 4 boys and 2 girls is 6! = 720
\nTotal number of ways of arranging them in such a way that both the girls sit together is (6-1)! * 2 = 240<\/p>\n

Hence, the answer is 720 – 240 = 480<\/p>\n

10)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

3 girls can be seated in 3! ways
\nThe required arrangement is B G B G B G B
\n4 boys can be seated in 4! ways
\nNumber of required ways = $3! \\times 4!$ = 144<\/p>\n

11)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

Let’s assume the sample size is 100. Let the number of male smokers be x.<\/p>\n

Total number of smokers = 3\/5 * 100 = 60<\/p>\n

Number of men = 1\/2 * 100 = 50<\/p>\n

Hence, number of male non-smokers is 50-x. Number of female smokers is 60-x and number of female non-smokers is x-10.<\/p>\n

Hence, probability of a person picked at random being a smoker and a male = x\/100<\/p>\n

As we do not know the value of x, we cannot determine the probability. Hence, option D.<\/p>\n

12)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

The total number of people is 8+6 = 14<\/p>\n

An easy way to calculate the number of ways of selecting atleast one woman is to calculate the opposite of it.<\/p>\n

The total number of ways of selecting 4 people from a total of 14 is $^{14}C_4 = 1001$
\nThe number of ways of selecting a group of all men (and no women) is $^8C_4 = 70$
\nHence, the number of ways of selecting 4 people such that atleast one of them is a woman is $1001-70 = 931$<\/p>\n

13)\u00a0Answer\u00a0(E)<\/strong><\/p>\n

The number of possible combinations is 2 * 2 * 2 = 8<\/p>\n

The probability that none of the children is a girl is 1\/8<\/p>\n

Option e) is the correct answer.<\/p>\n

14)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

The number of ways = Two men and one woman + One men and two women
\n= $\\frac{3C2 * 2C1}{5C3} + \\frac{3C1 * 2C2}{5C3}<\/p>\n

= \\frac{6+3}{20}<\/p>\n

= 9\/20<\/p>\n

Hence, the correct option is C.<\/p>\n

15)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

The total number of ways in which 4 children can be selected is $^8C_4 = 70$<\/p>\n

The number of favorable ways in which this can be done is $^5C_4 = 5$<\/p>\n

Hence, the required number of ways equals $\\frac{5}{70} = \\frac{1}{14}$<\/p>\n
