Options
\[\frac{1}{3}\]
\[\frac{3}{7}\]
\[\frac{1}{6}\]
\[\frac{1}{2}\]
Solution
A letter is selected from the word “MOBILE”
TO FIND: Probability that the letter chosen is a vowel
Total letter in the word “MOBILE” is 6
Vowels in the word “MOBILE” are ‘O’.’I’,’E’
Hence total number of favorable outcome is 3 i.e. ‘O’.’I’,’E’
`"We know that PROBABILITY" = "Number of favourable event"/"Total number of event"`
Hence probability that the letter chosen is a vowel `3/6=1/2`
