The theoretical probability of selecting a consonant at random from a list of
letters in the alphabet is 21. Wayne opens a book, randomly selects a letter on
the page, and records thé fetter. He repeats the experiment 200 times. He Fins
(consonant) = 60%. How does the theoretical probability differ from the
experimental probability? What are some possible sources for this discrepancy?


Sagot :

Vowels = {a, e, i, o, u}

There are 5 vowels out of 26 letters in the English alphabet. This leaves 26-5 = 21 consonants.

The theoretical probability of getting a consonant is 21/26 = 0.8077 = 80.77% approximately

Wayne found the empirical probability of a consonant as 60% which is quite a distance away from the 80.77% mentioned. The discrepancy is likely because vowels are tended to be used quite often in many words.

Words that are composed of consonants only are quite rare, but they do happen. Example: "fly" is a word with only consonants. I'm considering y to be a consonant.
