Answer:
0.316
Step-by-step explanation:
Probability = (number of outcomes)/(total number of outcomes)
In this case,
the total number of outcomes is 6+5+8 = 19, and
the number of outcomes for getting a blue pen = 6
Hence,
P(blue) = 6/19 = 0.31578947368 ≈ 0.316

Answer:
yes you can
Step-by-step explanation:
you just need too show ur work
The first step is to find out how question in total she is able to miss, while still passing.
We know that there are questions on the test and she must get % of the questions correct.
Let's calculate how many questions that is:
40 x 0.70
= 28.
<em>Subtract</em>
<em>40 - 28 </em>
<em>= 12.</em>
She is able to get 12 answers incorrect.
Now we must find out how many questions she got wrong when she got 40% of the first 15 correct.
If she got 40% correct; She got 60% incorrect.
Let's do the math:
<em>Multiply:</em>
<em>15 x 0.40</em>
<em>= 6</em>
<em>Subtract:</em>
<em>15 - 6 </em>
<em>= 9</em>
This means that she got 6 questions correct, and 9 questions incorrect.
With the total allotment of 12 incorrect answers allowed, she can only get 3 more questions wrong.
Now we must find the percentage of the remaining 25 questions she can get wrong.
She can only get 3 wrong and she must get 22 correct.
<em />
<em>Multiply:</em>
<em>22 x 4 </em>
<em>= 88.</em>
This means that she has to get 88% of the remaining 25 questions correct.
<em />
4x^2/2x^2
Bth x^2 will cross each other
And only this will be left
2
104 because 30% of 40=12 and 12*4people=48 seet
70% of 40 =28 and 28 *2 people =56 seets and add them all = 104
