For N dice, what is the % of rolling a 5 or 6 (a hit)?

1 D6
1 hits 33%
0 hits 66%

2 D6
2 hits 11%
1 hits 44%
0 hits 44%

3 D6
3 hits 4%
2 hits 22%
1 hits 44%
0 hits 30%

4 D6
4 hits 1%
3 hits 10%
2 hits 30%
1 hits 40%
0 hits 19%

5 D6
5 hits 0.4%
4 hits 4%
3 hits 16%
2 hits 33%
1 hits 33%
0 hits 13%

6 D6
6 hits 0.1%
5 hits 2%
4 hits 8%
3 hits 22%
2 hits 33%
1 hits 26%
0 hits 9%


The actual Excel formulae I came up with is
=FACT(A4)/(FACT(B4)*FACT(A4-B4))*(1/3)^B4*(2/3)^(A4-B4)
A column is number of dice rolled.
B column is the expected number of hits. A >= B >=0
1/3 is the chance of a 5 or 6 being rolled on a D6.
2/3 is the chance of a miss.
