In the example you've given, btw, the relevant calculations would be:
P(3 wins) = 56%*64%*54% ≈ 19.35%
P(2 wins) = (1-56%)*64%*54% + 56%*(1-64%)*54% + 56%*64%*(1-54%) ≈ 42.58%
P(1 wins) = (1-56%)*(1-64%)*54% + 56%*(1-64%)*(1-54%) + (1-56%)*64%*(1-54%) ≈ 30.78%
P(0 wins) = (1-56%)*(1-64%)*(1-54%) ≈ 7.29%
Obviously, the more games you were to include the more involved the calculations would become. This is why I'd recommend just downloading the template and letting the P2L() function do all the work for you.
