    Answer:

    Probability of selecting a ball from the first ball if it is a blue ball =  = 0.75

    Step-by-step explanation:

    Number of blue balls in the first box = 3

    Number of blue balls in the second box = 1

    Total number of blue balls = 3 + 1

    Total number of blue balls = 4

    Probability = (Number of possible outcomes)/(Number of total outcomes)

    Probability of selecting a ball from the first ball if it is a blue ball = 3/4

    Probability of selecting a ball from the first ball if it is a blue ball =  = 0.75
