Question

A bag contains each letter of the alphabet. Find the probability that a randomly selected letter from the bag will not be one of the five vowels.

Answer 1

To answer this question we will use the theoretical probability that an event occurs:

`\frac{favorable\text{ }cases}{Total\text{ }cases}.`

We know that there are 26 letters in the alphabet, then there are 21 letters that are not one of the five vowels.

Therefore the theoretical probability of choosing a letter that is not one of the five vowels is:

`(21)/(26).`

Answer:

`(21)/(26).`
