A particular operation has six components. Each component has a failure probability q, independent of any other component. The operation is successful if both
• Components 1, 2, and 3 all work, or component 4 works.
• Either component 5 or component 6 works.
Sketch a block diagram for this operation similar to those of Figure 1.3 on page 38. What is the probability P[W] that the operation is successful?
