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%.
Probability of choosing a consonant from math = 3/4
If the card is drawn at random, then the probability is 2/13.
The probability is 2:7.
Isosceles Triangle Thats 17 letters...unless you count the space as a letter. But that is the logical answer.
It is the first letter of the Greek alphabet which can be used, in geometry or algebra, to represent angles. In probability it can be used to represent a Type I error.
1/6 if the letter is chosen at random.
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.
2/11
Probability of choosing a consonant from math = 3/4
The probability is 2/11.
the answer is 1 out of 26
What the answer
It is 1/6.
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.
4 because in word perseverance we have 4 letters E
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%
There are 11 letters in the word mathematics. 2 of those 11 are A's. Probability is therefore 2/11.
