We got an assignment involving probability using Lindt Truffles

Assorted bag of 36 which include Milk Chocolate, Dark Chocolate, White Chocolate, Caramel and Extra Dark. Normal Serving Size is 3 pieces per serving, but in this problem. The person is taking 1 piece during the day spread out over 6 hours:

Opening a new bag - He randomly picked the following: 11 am 1 milk chocolate, 1 pm 1 milk chocolate, 2pm 1 caramel, 3pm 1 white chocolate, 4pm 1 white chocolate, 5pm 1 Extra Dark

Opening another new bag what is the probability of choosing the same pieces over the course of a new day.

How do the probabilities change if the Extra dark is put back and replaced with another choice? What is the probability of getting a 3rd milk or white chocolate, if that extra dark is replaced?

Which gives the Higher Probability?
