During World War II the German Forces Launched "Flying-Bombs" (Missiles)

Essay

During World War II The German forces launched "flying-bombs" (missiles) against London. In a study of the effectiveness of these flying-bombs, a researcher divided the south of London into 575 squares of area equal to 0.25 square km and counted the number of these squares that had sustained exactly k hits. The data for 0 - 4 hits in an area is given in the table below. Let the random variable x = number of flying-bombs hitting in a randomly selected square in south London. ​
Probability histogram ​
b)Using your estimated probabilities in part (a), estimate the following:
i)P(x = 1), the probability that 1 flying bomb hit in a randomly selected square.
ii)P(x < 3), the probability that fewer than 3 flying bombs hit.
iii)P(x ≥ 3), the probability that at least 3 flying bombs hit.
