Even Face Distribution
Combinatorics
Multinomial
Medium
Hint 1
Count sequences using the multinomial coefficient, then divide by total sequences.
Hint 2
There are equally likely sequences of rolls.
Show worked solution
1. Count favorable sequences
Number of sequences where each face appears exactly 6 times is the multinomial coefficient .
2. Total sequences
Total possible sequences of 36 rolls is .
3. Probability
Divide favorable by total.
Answer: 36! / ((6!)^6 * 6^36)
