A high school probability problem! Urgent! Thank you ~

There are three possibilities to draw the same sugar. There are C5/3= 10 kinds of orange sugar, C4/3=4 kinds of lemon sugar and C3/3= 1 0 kinds of lime sugar, that is, there are 10+4+65438 kinds of the same sugar.

There are 5*4*3=60 kinds of candy with three different flavors, and the probability that three pieces of candy are three different flavors is 60/220=3/ 1 1≈0.27.
