Using probability concepts, we have that:
a) The probability of selecting a card is of .
b) probability that on any turn you will not get to spin again.
c) Losing a turn is more likely.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
Item a:
The sum of all probabilities, which are 1/4, 5/12 and x(selecting a card) is 1, hence:
The probability of selecting a card is of .
Item b:
probability of spinning again, hence:
probability that on any turn you will not get to spin again.
Item c:
The probability of selecting a card is of .
The probability of losing a turn is , hence it is more likely.

If you have to do 70% of your projects and you have 3, you can approach this problem by showing that each project is 33.3% (I did 100/3 to determine what percentage each project is worth).
If we do one project, 33.3% is completed
If we do two projects, 66.6% is completed
If we do three projects, 100% is completed
Since we have to do at least 70%, we must do all three projects.
Answer: 1 11/24
<u>Do Keep Change Flip (KCF)</u>
Keep: 7/12
Change: ÷ into ×
Flip: 2/5 into 5/2
Your new problem should be 7/12*5/2
<u>Multiply</u>
7/12*5/2=35/24
<u>Turn 35/24 into a Mixed Number (Dvide)</u>
35÷24 = 1 11/24
4/8 and 5/8
The two denominators have a least common multiple of 8.
So 2/4 would turn into 4/8.
The second fraction is over 8, so you don’t need to change that one.
Answer:
8.3%
Step-by-step explanation:
A worker is paid from noon to 3 pm. So the worker works for 3 hours.
To find the percentage, we need to have the same units.
To do this, convert 3 hours to minutes and get 180 minutes.
We can now write a fraction (break minutes/total work time) to find the percent of the number of minutes in their break as a part of their whole paid shift.
This fraction is 15/180.
We can now simplify this fraction to 1/12.
Then convert into decimal form and get 0.0833.
Finally convert this decimal into a percentage by multiplying by 100 and get 8.3%
