Question

4.128 The weekly repair cost $ Y $ for a machine has a probability density function given by \[ f(y)=\left\{\begin{array}{ll} 3(1-y)^{2}, & 0<y<1, \\ 0, & \text { elsewhere } \end{array}\right. \] with measurements in hundreds of dollars. How much money should be budgeted each week for repair costs so that the actual cost will exceed the budgeted amount only $ 10 \% $ of the time?
