Okay, so I'm playing a phone game called Fire Emblem Heroes. You have the option to unlock a set of 5 random heroes, one at a time. Some are more rare and powerful than others. A single unlock has this distribution:
3-star Hero: 58%
4-star Hero: 36%
5-star Hero: 6%
How do I go about calculating the most likely combination? My common sense is telling me that the most common combination is pulling zero 5-stars, two 4-stars, and three 3-stars. Also, how would I go about calculating a specific combination (like... getting two 5-star heroes and three 3-star heroes?)
