Homework Statement
assume the dispersion of 3000 bombs launched from an aircraft showed a normally distributed miss distance profile with standard deviation of 10 meters. if 80 bobmbs are dropped on a target with no systematic errors at launch , what is probability that 50 bombs are within 10 meters of target.
Mean was not given but i think it should be assumed as zero
The Attempt at a Solution
mean = 0
std deviation = 10
x = 10
z1 = ( x - mean ) / std deviation
calculated p( z < z1) from normal distribution tables
then how to apply it for 50 bombs out of 80
