5.       Given set A = {2, 3, 4, 5} and Set B = {11, 12, 13, 14, 15}, two numbers are randomly selected, one from each set. What is probability that the sum of the two numbers equals 16?
(A) 0.20              (B) 0.25
(C) 0.30                         (D) 0.33
Explanation:
There are 20 possible pairs from set A and set B.(5x4=20)
Out of which four pairs have sum 16.
(2, 14), (3, 13), (4, 12), (5, 11)
Probability = Favorable Outcomes/Total Outcomes
Probability = 4/20 = 0.20

8.       The pie chart below has the breakup of the number of students from different departments in an engineering college for the year 2012. The proportion of male to female students in each department is 5:4. There are 40 males in Electrical Engineering. What is the difference between numbers of female students in the Civil department and the female students in the Mechanical department?
Explanation:
No. of male students in Electrical Engineering = 40
Proportion of male to female students in each department is 5:4
Total no. of female students in Electrical Engineering Dept = 40 x (4/5) = 32
Total no. of students in Electrical Engineering Dept = (40 + 32) = 72 (which is 20%)
Total no. of students in the college = 72 x (100/20) = 360
Total no. of students in Civil department = 360 x (30/100) = 108
Total no. of female students in Civil Dept = 108 x (4/(5+4)) = 108 x (4/9) = 48
Total no. of students in Mechanical Dept = 360 x (10/100) = 36
Total no. of female students in Mechanical Dept = 36 x (4/9) = 16
The difference is 48 – 16 = 32.
9.       The probabilities that a student passes in Mathematics, Physics and Chemistry are m, p and c respectively. Of these subjects, the student has 75% chance of passing in at least one, a 50% chance of passing in at least two and a 40% chance of passing in exactly two. Following relations are drawn in m, p, c:
(I) p + m + c = 27/20
(II) p + m + c = 13/20
(III) (p)×(m)×(c) = 1/10
(A) Only relation I is true
(B) Only relation II is true
(C) Relations II and III are true.
(D) Relations I and III are true.
Explanation:
1 - (1 - m) (1 - p) (1 - c) = 0.75                                     ..............(1)
(1 - m)pc +  (1 - p)mc + (1 - c)mp + mpc = 0.5          ..............(2)
(1 - m)pc +  (1 - p)mc + (1 - c)mp  = 0.4        ..............(3)

From equations (2) and (3), we get, mpc = 0.1 = 1/10

After simplifying equation (1), we get.
p + c + m - (pc + mc + mp) + mpc = 0.75
p + c + m - (pc + mc + mp) = 0.75 – mpc = 0.65
p + c + m - (pc + mc + mp) = 0.65                              ..............(4)

After simplifying equation (3), we get
pc + mc + mp - 3mpc = 0.4
pc + mc + mp = 0.4 + 3mpc = 0.4 + 3 x 0.1 = 0.7

After putting above value in equation (4), we get
p + c + m - 0.7 = 0.65
p + c + m = 1.35 = 27/20
