You randomly select one card from a 52-card deck. Find the probability of selecting the king of diamonds or the ace of spades. The probabilitiy is nothing. (Type an integer or a fraction. Simplify your answer.)

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.
