Question 1193177
<font color=black size=3>
Given Data
<table border = "1" cellpadding = "5"><tr><td></td><td>Electrical%</td><td>Mechanical%</td><td>Appearance%</td><td>Totals%</td></tr><tr><td>During Guarantee Period</td><td>18</td><td>13</td><td>32</td><td>63</td></tr><tr><td>After Guarantee Period</td><td>12</td><td>22</td><td>3</td><td>37</td></tr><tr><td>Totals</td><td>30</td><td>35</td><td>35</td><td>100</td></tr></table>


A = complaint due to appearance
B = complaint happens during guarantee period


P(A | B) = P(A given B)
Since we're given event B has definitely occurred with 100% certainty, this means we focus solely on the row labeled "During Guarantee Period". Everything else is irrelevant. 


We have 32% of the customers complaining about the appearance in this row, out of 63% total. We can treat these values as 32 and 63 without the percent signs.


Dividing said values gets us: 32/63 = 0.5079 = 50.79%


Answer as a fraction: 32/63
Answer in decimal form (approximate): 0.5079
Answer in percent form (approximate): 50.79%
