### One letter is randomly selected from the word math and a second letter is randomly selected from the word jokes what is the probability that both letters are vowels?

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%

### How does the contestant of Wheel of Fortune use probability?

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.

###### Asked in Probability

### What is the probability of choosing a vowel in the alphabet?

The answer depends on
the 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), and
whether 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.

###### Asked in Math and Arithmetic

### One letter is chosen at random from the word isosceles what is the probability of choosing?

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%.

### What is the probability of drawing a vowel from the word mathematics?

You have a total of 11 letters in "mathematics" and you have 4
vowels (a,e,a,i) so the probability of drawing a vowel is 4/11.
In other words if you were to consider the vowel's to be 1's and
the consonants 2's. What is the probability of drawing a "1". There
would be 4 1's and 7 2's. It would be 4/11

###### Asked in Probability

### What is the probability that a letter picked at random is not a vowel?

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

###### Asked in Probability

### What is the probability that the vowel is before j?

The answer depends on what language you refer to. It also
depends on which particular vowel is being referred to as
"the vowel".
Then you would need to know the number of words in that language
that contained a j as well as those that contained a j after
the vowel. The second number divided by the fist would give
the required probability.
