A) 5
B) 6
C) 7
D) 8
Correct Answer: B
Solution :
[b] There are 13 letters in the word 'ASSASSINATION' out of which one letter can be chosen in 13 ways. |
Hence, total number of outcomes =13 |
There are 5 vowels in the word 'ASSISSINATION'. |
So, there are 6 ways of selecting a vowel. |
Hence, required probability \[=\frac{6}{13}\] |
But given that, \[\frac{6}{2x+1}=\frac{6}{13}\] |
\[2x+1=13\,\,\,\,\Rightarrow \,\,\,\,2x=12\] |
\[x=6\] |
