Successful implementation of a new system is based on three independent modules. module 1 works properly with probability 0.96. for modules 2 and 3, these probabilities equal 0.95 and 0.90. compute the probability that at least one of these three modules fails to work properly.

The random variable x is defined as the number marking the sector in which the arrow lands when the spinner in the diagram is spun once.
