Please answer the question correctly...ill upvita you if you can amswer
A particular car toy works if all 10 of its component devices work. Each car toy is tested before leaving the factory. Each working car toy can be sold for k ringgit, but each nonworking car toy is worthless and must be thrown away. Each car toy can be built with either ordinary components or ultrareliable components. An ordinary component has a failure probability of q = 0.1 while an ultrareliable component has a failure probability of q/2, independent of any other component. However, each ordinary component costs RM 1 while an ultrareliable device cost RM 3. Discuss whether you should build your circuit with ordinary components or ultrareliable components in order to maximize your expected profit E[R]? Noted that your answer will depend on k.
