4. use a model to draw this equation. 7 divided by 7/9 5. write a word problem for this expression, 3÷1/3

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.
