"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 probability for a single random choice, is 6/13.
4/11
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.
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.
1 in 5
The answer depends onthe alphabet that you chose,whether or not you consider y to be a vowel,whether or not each letter is equally likely to be chosen (eg not from a bag of scrabble tiles), andwhether or not the choice was random.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.
3 in 8, 0.375, if you consider the y as a consonant, 4 in 8, 0.5, if not.
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.
It's not specified what exactly you want to find the probability of, but as a general rule: The word "isosceles" has nine letters, so your denominator will be nine because that is the number of possible choices. To find the numerator, determine how many letters meet the criteria or criterion you want to satisfy. For example: If you want to find the probability of choosing the letter s: there are three "s"s in the word "isosceles," so your numerator would be three, giving you a fraction of 3/9, which reduces to 1/3. If you want to find the probability of choosing a vowel: there are four vowels (i, o, e, e), so your probability would be 4/9. The same principle applies regardless of how the question ends (the probability of choosing ____). Remember that if you want your answer as a percent, you can simply divide the fraction and multiply by 100%.
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.
When they choose the letters R, S, T, L & N first they are choosing the most probable letters. When they choose to purchase an I after seeing the NG at the end of a word they are choosing the most probable vowel at that location and able that the vowel may still be used elsewhere.When they purchase the E vowel first the are buying the vowel that is used most. When they guess a H after seeing a three letter word beginning with a T they are not using the letter with the highest probability which would be buying the E to confirm that the word is likely the and if it is not the E is likely used elsewhere.
