An area of 100 acres is getting bombed. Mr X's property has an area of 1 acre. 400 bombs are thrown in to the area, what is the probability that a bomb will hit Mr X's property?

Answer 1

the probability of a bomb hitting the property is 1/100. Therefore the probability of it not hitting is .99.

the probability of all 400 bombs not hitting is (.99)^400= .01795

therefore the probability of any of the bombs hitting is ( 1.00) - (.01795) = 98.2%
