Three cannons are firing at a target. If their individual probabilities to hit the target are 0.2, 0.1, and 0.7 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 Choose the most appropriate option
A) 0.061	B) 0.12	C) 0.218	D) 0.216	E) 0.941
The probability that eachdoesn'thit is: 0.8, 0.9, and 0.3. When we have multiple independent events, we multiply the probabilities:   .8*.9*.3 = 0.216.   Option: 0.216
