    Answer:

    The probability he will roll a 5 is 0.167.

    Step-by-step explanation:

    Minh has a 6-number cube it has a different number on each side.

    The number on each side are: 4, 5, 6, 7, 8 or 9.

    As there are different number on each face of the cube, on every roll the possible outcomes are:

    S = {4, 5, 6, 7, 8 or 9}

    n (S) = 6

    The probability of an event E is the ratio of the favorable number f outcomes to the total number of outcomes.

    P(E)=\frac{n}{N}

    Compute the probability of rolling a 5 as follows:

    P(E)=\frac{n}{N}\\P(5)=\frac{1}{6}\\=0.167

    Thus, the probability he will roll a 5 is 0.167.
