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%

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.
There are eight different letters in 'mathematics' - a, c, e, h, i, m, s and t. Since there are 26 letters in the alphabet, the chance of a randomly chosen one being a letter that's in mathematics is 8/26, or 4/13.
I think it depends on how many students are thinking of alphabet letters at the same time :) The first student will think of a letter from the English alphabet. Then, the second student will think of a letter. The probability that the second student will select what the first student selected is 1/26.
The answer depends on which letters are in the bag!

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.
Until the letter is selected, it is a variable. Immediately after it is selected, the outcome is no longer a variable but a constant.
There are five letters, and two of them are s's. The theoretical probability of choosing an s would be 2 out of 5.2/5 or 40%
If the letters of computer are randomly arranged in all possible ways, the probability the word begins with a vowel in five out of 26, or 0.1923. You do not need to consider any other letters, or any permutations or combinations, because you only asked about the first letter.

5/24, or five out of twenty four, or with numbers, five out of infinity

The probability is 1. The letters in the word mathematics are all constants, not variables!
