Options

• 1

• \[\frac{4}{5}\]

• \[\frac{1}{26}\]

• \[\frac{1}{5}\]

Answer 1

Out of the vowels of English alphabet, one letter is selected at random. The probability of selecting the letter ‘O’ is \[\underline{\boldsymbol{\frac{1}{5}}}\].

Explanation:

Vowels of english alphabet : a, e, i, o, u.

Since, there is one letter ‘o’ in the vowels.

\[\therefore \text{No. of favourable outcomes} = 1\]

\[\text{P(selecting the letter ‘O’)} = \frac{\text{No. of favourable outcomes}}{\text{Total no. of possible outcomes}} = \frac{1}{5}.\]
