    2/45

    Step-by-step explanation:

    Note this selection is done without replacement hence after each selection sample size will reduce

    Given data

    Samples 3 chocolate chip bars,

    2 peanut butter bars,

    1 lemon bar, and

    4 raisin bars

    Sample size S = [3+2+1+4] = 10

    Probability that first selection is lemon = 1/10

    Probability that second selection is raisin = 4/9

    Hence the probability that the first bar Iesha selects will be lemon and the second will be raisin = 1/10*4/9

    = 4/90 = 2/45
