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!
The sample space is {p, r, o, b, a, i, l, t, e, s}
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
Probability of choosing a consonant from math = 3/4
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.
The sample space consists of the letters of the word "PROBABILITY" = {P,R,O,B,A,I,L,T,Y}
2/11
The probability is 2/11.
1/6 if the letter is chosen at random.
There are 11 letters in the word mathematics. 2 of those 11 are A's. Probability is therefore 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!
The odds are 2/11 (two out of eleven), or 18.18%.
The sample space is:SM, PM, AM, CM, EM, ST, PT, AT, CT, ET, SH, PH, AH, CH, EH.
The sample space is {p, r, o, b, a, i, l, t, e, s}
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%.
