When you multiply 3 1/4 by a number greater than one, you will get the answer greater than 3 1/4.
The total cost of her haircut was 28 dollars
step by step:
(percentage) 15 x 6 = 90
4.20 x 6 =25.2
(perscentage) 15 divided by 3 = 5
4.20 divided by 3 = 1.4
1.4 + 1.4 = 2.8
25.2 + 2.8 =28
Using the <u>arrangements and the probability concept</u>, it is found that there is a 0.75 = 75% probability that the number formed is not divisible by 4.
- A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
- The number of possible arrangements of n elements is given by

In this problem, there are 4 elements, hence
.
A number is a multiple of 4 if the <u>number composed by it's last 2 digits are multiples of 4</u>.
- Hence, the possible options for the last 2 digits are: 56, 68, 76.
- For each of them, there are
options for the first 2 digits, hence, there will be 2 x 3 = 6 multiples of 4.
The other 18 numbers formed are not divisible by 4, hence:

0.75 = 75% probability that the number formed is not divisible by 4.
