If a carton containing a dozen glass is dropped, which of the following cannot be the ratio of unbroken glasses to broken glasses?
1). 2 : 1
2). 3 : 1
3). 3 : 2
4). 7 : 5
Let the broken pieces out of 12 be x
⇒ The Glass not broken = (12 - x)
Ratio of Unbroken : Broken = x : (12 - x)
⇒ Now For x = 1 ⇒ Ratio = 1 : 11
⇒ Now For x = 2 ⇒ Ratio = 2 : 10 = 1 : 5
⇒ Now For x = 3 ⇒ Ratio = 3 : 9 = 1 : 3
⇒ Now For x = 4 ⇒ Ratio = 4 : 8 = 1 : 2
⇒ Now For x = 5 ⇒ Ratio = 5 : 7
⇒ Now For x = 6 ⇒ Ratio = 6 : 6 = 1 : 1
⇒ Now For x = 7 ⇒ Ratio = 7 : 5
⇒ Now For x = 8 ⇒ Ratio = 8 : 4 = 2 : 1
⇒ Now For x = 9 ⇒ Ratio = 9 : 3 = 3 : 1
⇒ Now For x = 10 ⇒ Ratio = 10 : 2 = 5 : 1
⇒ Now For x = 11 ⇒ Ratio = 11 : 1
Clearly on comparing various ratios we find that ratio which is not possible is 3 : 22. What is the probability of choosing a vowel from the word Mississippi?
