: A string of 10 lightbulbs is wired in such a way that if : any individual lightbulb fails, the entire string fails. If for : each individual lightbulb the probability of failing during : time period T id 0.06, what is the probability that the : string of lightbulbs will fail during time period T? : A.0.06 : B.(0.06)^10 : C.1-(0.06)^10 : D.(0.94)^10 : ﹡ E.1-(0.94)^10 : 这题题目看不大懂... : GWD27 : Q31: : A certain quantity is measured on two different scales, the R-scale and the : S-scale, that are related linearly. Measurements on the R-scale of 6 and 24 : correspond to measurements on the S-scale of 30 and 60, respectively. What : measurement on the R-scale corresponds to a measurement of 100 on the S-scale? : A. 20 : B. 36 : ﹡C. 48 : D. 60 : E. 84 : 我算D...不知道是不是我算错了... : 麻烦帮我解答一下...谢谢!! 第一题问的是在T这个期间之内这串灯泡不亮的机率，由於一颗灯泡不亮就会造成整串灯 泡不亮，因此整串不亮的机率为1减这10颗灯泡都亮的机率，10颗灯泡都亮着的机率为0.94 的10次方，故为1-(0.94)^10。 --
