Answer:
This is 0.14 to the nearest hundredth
Step-by-step explanation:
Firstly we list the parameters;
Drive to school = 40
Take the bus = 50
Walk = 10
Sophomore = 30
Junior = 35
Senior = 35
Total number of students in sample is 100
Let W be the event that a student walked to school
So P(w) = 10/100 = 0.1
Let S be the event that a student is a senior
P(S) = 35/100 = 0.35
The probability we want to calculate can be said to be;
Probability that a student walked to school given that he is a senior
This can be represented and calculated as follows;
P( w| s) = P( w n s) / P(s)
w n s is the probability that a student walked to school and he is a senior
We need to know the number of seniors who walked to school
From the table, this is 5/100 = 0.05
So the Conditional probability is as follows;
P(W | S ) = 0.05/0.35 = 0.1429
To the nearest hundredth, that is 0.14

Answer: <em>third from the top</em>
Step-by-step explanation:
<em>The correct answer is third from the top.</em>
<em>Arranging numbers in ascending order: </em>
<em>15 17 17 17 18 18 18 19 19 19 21 21 22 23 24</em>
<em>Let's count how many times each number occurs in this series of numbers.</em>
<em>row of numbers</em>
<em>15 </em>+
<em>16 not</em>
<em>17 </em>+ + +
<em>18 </em>+ + +
<em>19 </em>+ + +
<em>20 not</em>
<em>21 </em>+ +
<em>22 </em>+
<em>23 </em>+
<em>24 </em>+
<em>25 not</em>
Well if your having trouble you should stay after school and ask for help that's what I would do.
