In a jar, there are 60 candies as follows:
12 chocolate candies,
12 strawberry candies,
12 vanilla candies,
12 orange candies,
12 coffee candies.
All candies have the same and identical wrappers. You are asked to take a number of candies so that at least you get four different flavors (for example, you may get: 1 chocolate candy, 1 strawberry, 1 orange, candy, and 1 vanilla candy; or 1 vanilla candy, 1 chocolate candy, 1 orange candy, and 1 coffee candy; etc). What is the minimum number of candies should you take if the candies are taken randomly?
please help

There are two questions that can be made.
1) What is the minimum possible number of candies that can be picked to get 4 different candies.
Answer will be 4, as you will take the best possible scenario.
2) What is the minimum number of candies that should be picked to be sure to get 4 different candies.
Answer will be 3*12+1=37.
In this, you will take the worst scenario, that is you keep getting 3 particular types till all of them are picked, so 3*12. Now whatever you pick will give you the 4th type of candy.
