Question 1104043
<br>
Solve this kind of problem by considering a "worst case" scenario.<br>
If you want to get three brown candies, the worst that can happen is that you get all of the other candies before you get any brown ones.<br>
So the first 45 candies are the 20 red and 25 green; then you need to pick three more candies to get three brown.<br>
20+25+3 = 48.
