Question 1197569
<font color=black size=3>
Problem 1


This is what the chart of values looks like<table border = "1" cellpadding = "5"><tr><td></td><td>Voted for A</td><td>Did not vote for A</td><td>Total</td></tr><tr><td>Voted for B</td><td>25</td><td>375</td><td>400</td></tr><tr><td>Did not vote for B</td><td>175</td><td>425</td><td>600</td></tr><tr><td>Total</td><td>200</td><td>800</td><td>1000</td></tr></table>The phrasing "given they voted for B" means we focus on the "voted for B" row.


We have 400 people who voted for B.
Of this total, 25 also voted for A
25/400 = 1/16


Answer: <font color=red>1/16</font>

Problem 2


Refer to the chart in problem 1.


This time we focus on the "voted for A" column since we know 100% the person voted for this candidate.


Of the 200 people who voted for issue A, 25 voted for issue B.
25/200 = 1/8


Answer: <font color=red>1/8</font>
