The probability is 2/11.
The sample space is {m, a, t, h, e, i, c, s} which, curiously, is also the sample space for choosing a letter from my user name!
There are 11 letters and the m appears twice, so it is 2 in 11.
Mathematics
3 in 8, 0.375, if you consider the y as a consonant, 4 in 8, 0.5, if not.
4 because in word perseverance we have 4 letters E
There are 11 letters in the word mathematics. 2 of those 11 are A's. Probability is therefore 2/11.
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.
Probability of choosing a consonant from math = 3/4
2/11
The probability is 1. The letters in the word mathematics are all constants, not variables!
1/6 if the letter is chosen at random.
Probablity of picking up 3 vowels from the word MATHEMATICS Each of the letters in the word MATHEMATICS is on a letter tile in a bag
The sample space consists of the letters of the word "PROBABILITY" = {P,R,O,B,A,I,L,T,Y}
The sample space is {m, a, t, h, e, i, c, s} which, curiously, is also the sample space for choosing a letter from my user name!
The odds are 2/11 (two out of eleven), or 18.18%.
If picked at random, the answer is 2/11.
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%.
