Your right on 6 and 7 but I don't understand 10 @ 11
Step-by-step explanation:
Plan B:
2:5 = 0.4 red to 1 white
1:4 = 0.25 red to 1 white
Students might also scale up using part-to-whole-ratios and come up with 35 parts total and 14 parts red for Plan A and 35 parts total and 7 parts red for Plan B.
Using concepts of probability, it is found that there is a 4.7% probability that it arrives in Philadelphia (PHL).
<h3>What is a probability?</h3>
- A <em>probability </em>is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
- Over a large number of trials, a percentage can also represent the probability of single event.
In this question, researching the problem on the internet, we have that over a large number of flights, of those which arrived on time, 4.7% of them were in Philadelphia, hence:
- There is a 4.7% probability that it arrives in Philadelphia (PHL).

Answer:
<u>40%</u>
Step-by-step explanation:
Working out percentages
168 of 420 can be written as:
168
/420
420
To find percentage, we need to find an equivalent number with denominator 100. Multiply both numerator & denominator by 100
=(168/420)*(100)
= <u>40
/100
</u>
Therefore, the answer is <u>40%
</u>
If you are using a calculator, simply enter 168÷420×100 which will give you 40 as the answer.
