What is the probability of rolling a single die and it landing on 2 and 4?

Explanation:

When you roll on die you can only get one possible value facing up.  The expression "the probability of getting a 2 and 4"  means that they both occur at the same time.  Since you can not get two results with one die, the probability must be .

The difference between these two is .

Example Question #1 : How To Read Tables

A popular word game uses one hundred tiles, each of which is marked with a letter or a blank. The distribution of the tiles is shown above, with each letter paired with the number of tiles marked with that letter. Notice that there are two blank tiles.

In the game, the four letters that are the most difficult to play are the "J", the "Q", the "X", and the "Z". John and Jane, who are in third grade, agree to remove these letters. After this is done, what percent of the letter tiles are marked with consonants (Note: "Y" counts as a consonant)?

Explanation:

The easiest way to count the consonants is to count the vowels and blanks first.

There are nine "A" tiles, twelve "E" tiles, nine "I" tiles, eight "O" tiles, four "U" tiles, and two "blanks". This is a total of

tiles that are not consonants.

There are 96 tiles left after the removal of the "J", the "Q", the "X", and the "Z". Therefore, the number of consonants remaining is

, which is

This rounds to 54%.
