Question

Find the number of two-letter words that begin with a vowel.

• A. 105
• B. 130
• C. 546
• D. 25

Hint:

Fix the first letter based on condition (vowel), then count choices for the second independently.

Answer 1

The Correct Option is B

There are 5 vowels (A, E, I, O, U). The first letter must be one of these 5. The second letter can be any of the 26 English alphabets. \[ \text{Total such 2-letter words} = 5 \times 26 = 130 \]
