    The most recent freshman class at Loyola consists of 880 students. Of these, 500 identified themselves as "smokers?. Compute the empirical probability that a randomly selected freshman student from this class is not a "smoker"

    A) \[\frac{8}{22}\]                                

    B)        \[\frac{19}{44}\]              

    C)         \[\frac{15}{44}\]                                             

    D)         \[\frac{9}{44}\]

    Correct Answer: B

    Solution :

    Total students = 880 No. of smokers = 500 \[\therefore \]Non-smokers \[=880-500=380\] Now, required probability \[=\frac{380}{880}=\frac{19}{44}\]
