    Sonny goes to a store to purchase juice cartons for his Shop. The store has 80 cartons of Litchi juice, 90 cartons of pineapple juice. 38 cartons of mango juice and 42 cartons of banana juice. If Sunny chooses a carton at random, then answer the following questions:
     
    The probability that the selected carton is of pineapple juice is:

    A) \[\frac{1}{25}\] 

    B) \[\frac{8}{25}\]

    C) \[\frac{13}{25}\]

    D) \[\frac{9}{25}\]

    Correct Answer: D

    Solution :

    Total number of cartons in the store
    \[=80+90+38+42=250\]
    P(choosing a pineapple juice carton)
    \[=\frac{90}{250}=\frac{9}{25}\]
    So, Option [d] is correct.
