Which of the following is an equation for the sine wave graphed below?

y = 8 sin (1/2x)

y = 8 sin (x)

y = 8 sin (2x)

y = 8 sin (4x)

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.
