Answer & Explanation

 

Boys(270) Girls(90)
Pass Fail Pass Fail
162 108 30 60

 

 

  1. 3

Ratio = 90/108 = 5/6

 

  1. 4

Sum = 108 + 30 = 138

 

  1. 1

Diff = 162 – 60 = 102

 

  1. 2

Ratio = 192/168 = 8/7

 

  1. 4

Req% = 162/90 * 100 = 180%

 

  1. 2

n(S) = 15C3 = (15 * 14 * 13)/6 = 455

2 red balls can be selected in 4c2 = 6 ways

And remaining one ball can be selected in 11C1 = 11 ways

P(E) = (6 * 11)/455 = 66/455

 

  1. 3

n(S) = 15C3 = 455

 

Three balls have to be selected from 4 red and 6 white balls

No. of ways = 10C3 = 120

P(E) = 120/455 = 24/91

 

  1. 4

n(S) =15C3 = 455

 

If all three ball are of same colour, number of ways

= 4C3 + 5C3 + 6C3 = 4 + 10 + 20 = 34

P(E) = 34/455

For being different colour P(E) = 1 – 34/455 = 421/455

 

  1. 1

n(S) = 15C2 = 105

n(e) = 4C2 + 5C2 + 6C2 = 6 + 10 + 15 = 31

P(E) = 31/105

 

  1. 4

n(S) = 15C3 = 455

n(E) = 4C1 + 5C1 + 6C1 = 4 * 5 * 6 = 120

P(E) = 120/455 = 24/91
