The answer depends on
If a choice was random, from equal numbers of letters from the modern Roman alphabet and y is not considered a vowel then the answer is 5/26.
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
1 in 5
There are 26 letters and 5 vowels so 5/26.
Since the word "probability" contains only letters, then the probability of choosing a letter from the word "probability" is 1, i.e. it is certain to happen.
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.
The probability for a single random choice, is 6/13.
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

There are 26 letters and 5 vowels so 5/26.
"Puzzle" has 6 letters, and 2 of them are vowels. So the odds of choosing a vowel are 2/6, which equals 1/3, which is one-third or 33.33%.
The first vowel in the alphabet is "A."
3 in 8, 0.375, if you consider the y as a consonant, 4 in 8, 0.5, if not.
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
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 alphabet "A" is both a vowel and the name of a continent (Africa).
The fourth vowel in the alphabet is the letter "o."
The probability is 25/676 = 0.037, approx.
