    Answer:

    95 times

    Step-by-step explanation:

    Probability of rolling a 5 =1/6

    So no. of times 5 is expected when the number cube is rolled out 570 times = 570*1/6 = 95 times

    1)First determine the probability of rolling a 5

    2)Since you can only roll a 5 once in a 6-sided cube the probability is ⅙ or about 0.1667

    3)Multiply the probability and the total number of rolls

    .1667 * 570= 95

    Answer : 95 times
