作业:求算式 C(6000,3)*(0.0015)^3*(1-0.0015)^(6000-3)+C(6000,4)*(0.0015)^4*(1-0.0015)^(6000-4) 的值.
题型:数学计算
解:
C(6000,3)*(0.0015)^3*(1-0.0015)^(6000-3)+C(6000,4)*(0.0015)^4*(1-0.0015)^(6000-4)
=190607866*(0.0015)^3*(1-0.0015)^(6000-3)+C(6000,4)*(0.0015)^4*(1-0.0015)^(6000-4)
=190607866*0.0015^3*(1-0.0015)^(6000-3)+C(6000,4)*(0.0015)^4*(1-0.0015)^(6000-4)
=190607866*0.0015^3*0.9985^(6000-3)+C(6000,4)*(0.0015)^4*(1-0.0015)^(6000-4)
=190607866*0.0015^3*0.9985^5997+C(6000,4)*(0.0015)^4*(1-0.0015)^(6000-4)
=190607866*0.0015^3*0.9985^5997+(-25438054)*(0.0015)^4*(1-0.0015)^(6000-4)
=190607866*0.0015^3*0.9985^5997+(-25438054)*0.0015^4*(1-0.0015)^(6000-4)
=190607866*0.0015^3*0.9985^5997+(-25438054)*0.0015^4*0.9985^(6000-4)
=190607866*0.0015^3*0.9985^5997+(-25438054)*0.0015^4*0.9985^5996
=190607866*0.000000003375*0.9985^5997+(-25438054)*0.0015^4*0.9985^5996
=190607866*0.000000003375*0.000123132028083+(-25438054)*0.0015^4*0.9985^5996
=190607866*0.000000003375*0.000123132028083+(-25438054)*0.000000000005063*0.9985^5996
=190607866*0.000000003375*0.000123132028083+(-25438054)*0.000000000005063*0.000123317003588
=0.643302*0.000123132028083+(-25438054)*0.000000000005063*0.000123317003588
=0.000079+(-25438054)*0.000000000005063*0.000123317003588
=0.000079+(-0.000129)*0.000123317003588
=0.000079+-0
=0.000079 答案:C(6000,3)*(0.0015)^3*(1-0.0015)^(6000-3)+C(6000,4)*(0.0015)^4*(1-0.0015)^(6000-4)=0.000079你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
