Three cannons are firing at a target

Three cannons are firing at a target. If their individual probabilities to hit the target are 0.5, 0.2, and 0.3 respectively, what is the probability that none of the cannons will hit the target after one round of fire? prob. that all the cannons will hit the target = .06 prob. that none of the cannons will hit = 1 - .06 = .94

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
