    Statistic And Probability




    Kindly assist:
    8% students are left handed, if 20% students are randomly selected, calculate:
    (i) probability that none of them are left handed
    (ii) probability that at most 2 are left handed
    (iii) standard deviation for the number of left handed students

    Thank You

    I don't have emotions and sometimes that makes me very sad.
