Question 1082211
<table border=1><tr><td></td><td>Minor Flaw</td><td>No Minor Flaw</td><td>Total</td></tr><tr><td>Major Flaw</td><td>24</td><td>38</td><td>62</td></tr><tr><td>No Major flaw</td><td>71</td><td>417</td><td>488</td></tr><tr><td>Total</td><td>95</td><td>455</td><td>550</td></tr></table>

There are a total of 95 that have a minor flaw (add up the values in the "minor flaw" column 24+71 = 95). See bottom of column 1.


There are a total of 62 that have a major flaw (add up the values in the "major flaw" row 24+38 = 62). See end of row 1.


There are 95+62 = 157 that have either a minor or major flaw. We can add like this because of the mutually exclusive events. The flaw is major or it is minor. The flaw can't be both. There is no overlap. 


This is out of 550 packs total. 


P(major or minor flaw) = probability of getting a pack with either a major or minor flaw
P(major or minor flaw) = (# with major or minor flaws)/(# total)
P(major or minor flaw) = 157/550
P(major or minor flaw) = 0.285455 (approximate)
P(major or minor flaw) = 28.5455% (approximate)


The answer as a fraction is 157/550
The answer as a decimal is approximately 0.285455 
The answer as a percentage is approximately 28.5455%
