Question 1141624
Probability of picking an Anjou pear (before Bose pears are removed): 
<pr>
1 - 2/5 - 7/12 
<pr>
Simplify, using common denominator of 60:
<pr>
60/60 - 24/60 - 35/60 = 1/60
<pr>
So...the odds of picking each pear are as follows:
<pr>
Bartlett = 24/60
Bose = 35/60
Anjou = 1/60
<pr>
If you remove the Bose pears, then the odds of picking an Anjou pear are:
<pr>
{{{(1/60)/((1/60)+(24/60))}}}
<pr>
You can get rid of the denominator of 60 in each number so you are left with the much more manageable:
<pr>
{{{1/(1 + 24)}}}
<pr>
So...the final answer is 1/25.
