Homework Help: Aircraft bombing problem

  1. Aug 27, 2010 #1
    1. The problem statement, all variables and given/known data

    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

    3. 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
