To work out probability you have to know the number of possible options, and how many of those options meet the criteria. In this case there are 26 possible options (all the letters) and 21 that meet the criteria (21 non-vowels). The probability is the number that match divided by the total number possible. In this case it would be 21/26. This comes out to approximately 0.80769. Thus the probability that a letter picked at random is not a vowel is 0.80769
The probability that a letter picked at random is not a vowel depends on the set of letters you are choosing from. In the English alphabet, there are 21 consonants and 5 vowels, so the probability of picking a consonant is 21/26 or approximately 0.808.
4/11
if you only consider the vowels to be aeiou, then the answer is that you have a 5 out of 26 (or .19%) chance.
The probability for a single random choice, is 6/13.
5/24, or five out of twenty four, or with numbers, five out of infinity
Assuming that "voul" is a random way of spelling vowel, perhaps the shape is IRREGULAR.

Q. A letter is chosen at random from the word STATistician.What is the probability that it is a vowel?What is the probability that it is T.
Normally 5/26 but if you count "y" as a vowel, 6/26 or 2/13.
The word 'probability' has 11 letters and 5 of them are vowels (including the 'y'). Therefore the probability of picking a vowel is 5/11.
Probability is given as Desired Outcomes divided by total number of outcomes. For the probability of picking a vowel, desired outcomes are : a,e,i,o,u (5) Total no. of outcomes is the entire alphabet set from a to z (26) Hence, the required probabilty is 5/26
if you only consider the vowels to be aeiou, then the answer is that you have a 5 out of 26 (or .19%) chance.
The probability for a single random choice, is 6/13.
sample space=13 no of possible outcomes (vowel)=5/13 no of possible outcomes (consonant)=7/13
the answer is 1 out of 26
There are 10 letters in the word "aspiration" and 5 of them are vowels. The probability of a randomly-selected letter being a vowel are 5/10 = 1/2 = 0.50.
Word 1) 'math' has one vowel letter among a total of 4 letters. The probability of randomly selecting the vowel letter 'a' is P(v) = 1/4. Word 2) 'jokes' has two vowel letters among a total of 5 letters. The probability of randomly selecting a vowel letter is P(v) = 2/5. The probability of randomly selecting a vowel letter from the first word and a vowel letter from the second word is: P(v1,v2) = 1/4 (2/5) = 2/20 = 1/10 = 0.10 = 10.0%
