The probability that all 3 will be vowels will be .01 to the nearest hundredth

Probability is the study of the odds of an outcome occurring, which are determined by the ratio of favorable examples to probable cases.

There are 26 English alphabets, each with five vowels and twenty-one consonants. As a result, the likelihood of selecting a consonant's alphabet is 21/26.

First of all, we need to know the number of vowels in the 26 letters.

There are 5 vowels among the 26 letters,

probability (3 vowels of 3)
