What is a random letter?

A random letter is a letter picked casually over a defined set, of which it is not possible to predict future value based on past or present extractions.

What is a random letter generator?

A Random Letter Generator is a tool developed to generate one or a list of more random letters. It is possible to select language and the number of letters. You can even choose to display only uppercase or lowercase letters. Available languages are: English, Spanish, Chinese, French, German, Japanese, Russian, and Armenian. Once done, you simply press the "Generate" button and a list of words will appear.

What is the most random letter?

It is not possible to define a most random letter since the probability of picking a random letter is the same for all letters. But it is demonstrated that it is possible to identify most picked letters: when groups of people are polled to pick a random word the most commonly chosen letter resulted to be “J”. The second one is probably “X” from famous Mary Poppins book series.

Why generate random letters?

This tool can be very useful to generate creative ideas for writing a story, a blog post or even a song. For example, you could generate one random letter and start thinking about words beginning or ending with that letter. Then you can use all those words to build a crazy story using and training your creativity. This will force you to think creatively since you have no idea what letter will appear. You can also generate multiple letters and try to find a word that contains all of them.

How to generate a random letter?

The simplest way is to use our tool.
You can also generate a random letter manually opening a book or a dictionary and pointing a word with closed eyes. Also you can generate three random numbers (link to RNG) and use them to select one random letter from one page and one word from a physical book, an e-book or a PDF or Word document. If you prefer to use Microsoft Excel, there is a worksheet functions that are meant to generate random string from a list. Input all the letters in column A. Then select a blank cell on another column, copy and paste formula =INDEX($A:$A,RANDBETWEEN(1,COUNTA($A:$A)),1) into the formula bar, and then press the Enter key. You will see a random letter displayed in the selected cell.

Probability, random number analysis

Let’s start simple with some probability examples.
The probability of guessing correctly a letter in a list of 10 is 1/10 (10%)
The probability of guessing correctly a letter in a list of 20 is 1/20 (5%)
The probability of guessing correctly a letter in a list of 100 is 1/100 (1%)
The probability of guessing correctly 3 letter in a list of 100 is 1/100 x 1/100 x 1/100 = 1/1,000,000 (0.0001%)
This calculation is valid every time that the extractions are unpredictable and independent. But in the case of multiple choice answers for example, it is different because the independence condition is no longer verified: the same letter cannot be selected twice. In this case you can calculate the probability select the right 3 letters in a list of 10 in this way: the probability to guess correctly the first letter is 3/10, for the second letter is 2/9 and for the third letter is 1/8. The total probability is 3/10 x 2/9 x 3/8 = 6/720 = 1/120 (0.8333%)
