To find the probability of selecting a vowel on the first draw from the bag of letter tiles, we first calculate the total number of vowels based on the given distribution:
- Number of A tiles = 9
- Number of E tiles = 12
- Number of I tiles = 9
- Number of O tiles = 8
- Number of U tiles = 4
Now, let's calculate the total number of vowel tiles:
Total number of vowels = 9 (A) + 12 (E) + 9 (I) + 8 (O) + 4 (U) = 42
Next, the total number of tiles in the bag is 100 (as given).
The probability \( P \) of selecting a vowel on the first draw is given by the formula:
\[ P(\text{selecting a vowel}) = \frac{\text{Number of vowel tiles}}{\text{Total number of tiles}} = \frac{42}{100} \]
This can be simplified:
\[ P(\text{selecting a vowel}) = \frac{42}{100} = \frac{21}{50} \]
Now, from the options provided, the correct answer is:
21/50
