P(x>12 or x=12)
=1-P(x=11)-P(x=10)-P(x=9)-P(x=8)-P(x=7)-P(x=6)-P(x=5)-P(x=4)-P(x=3)-P(x=2)-P(x=1)-P(x=0)
=1-(75C11)(0.15)^11 (1-0.15)^(75-11)-(75C10)(0.15)^10 (1-0.15)^(75-10)-(75C9)(0.15)^9 (1-0.15)^(75-9)-(75C8)(0.15)^8 (1-0.15)^(75-8)-(75C7)(0.15)^7 (1-0.15)^(75-7)-(75C6)(0.15)^6 (1-0.15)^(75-6)-(75C5)(0.15)^5 (1-0.15)^(75-5)-(75C4)(0.15)^4 (1-0.15)^(75-4)-(75C3)(0.15)^3 (1-0.15)^(75-3)-(75C2)(0.15)^2 (1-0.15)^(75-2)-(75C1)(0.15)^1 (1-0.15)^(75-1)-(75C0)(0.15)^0 (1-0.15)^(75-0)
=0.454699553
