Correct option is C
Given:
The string of letters is:
R A M U K Y A J N A S
The total number of letters in the string is 11.
We are asked to find the probability that a randomly drawn letter is NOT a vowel.
Step 1: Identify the vowels in the string.
The vowels in the English alphabet are A, E, I, O, U.
From the given string, the vowels are:
- A, A, A (3 occurrences of 'A')
- U (1 occurrence of 'U')
Thus, there are 4 vowels in the string.
Step 2: Identify the total number of letters.
The total number of letters in the string is 11:
- R, A, M, U, K, Y, A, J, N, A, S (This is a total of 11 letters).
Step 3: Find the number of letters that are NOT vowels.
The number of letters that are NOT vowels is:
- Total letters = 11
- Vowels = 4
- Non-vowels = 11 - 4 = 7 (These are the consonants).
Step 4: Calculate the probability.
The probability of drawing a letter that is NOT a vowel is:
P(Not a vowel) = (Number of non-vowel letters) / (Total number of letters) = 7 / 11
P(Not a vowel)=Number of non-vowel lettersTotal number of letters=711P(\text{Not a vowel}) = \frac{\text{Number of non-vowel letters}}{\text{Total number of letters}} = \frac{7}{11}
Final Answer:
The probability that the letter drawn is NOT a vowel is 7/11.
Correct Option:(c) 7/11.
