this is a binomial problem
probability of hit (h) = .193
probability of no hit (n) = 1 - .193 = .807
at least 2 means not zero and not one
(n + h)^7 = n^7 + 7 n^6 h...
p(h ≥ 2) = .807^7 + (7 * .807^6 * .193)
probability of hit (h) = .193
probability of no hit (n) = 1 - .193 = .807
at least 2 means not zero and not one
(n + h)^7 = n^7 + 7 n^6 h...
p(h ≥ 2) = .807^7 + (7 * .807^6 * .193)
