Answer 1

The word "Mathematical" has 12 letters, and 3 of them are the letter "A".
- 3/12, or 1/4 of the letters will be "A"
- This is equivalent to .25 as a decimal 
- To find the percent, you multiply a decimal by 100, to get 25%

The 3 on a number cube appears 1/6 times
- theoretically, 1/6 of the rolls will be a 3
- as shown by the experiment, 67/450, which is the simplest form of this probability 

 There are 3 even numbers on a dice, which are half the numbers 
- 1/2 of the rolls will be even
- 5/6 of the rolls will not be the number 2, since 2 only appears on a die once

Since there are 144 martial arts students, and 7/12 of them practice daily, you multiply the terms to find how many practice on a daily basis
- 84 students practice on a daily basis
- the sample size of this experiment is 122 students
