#1**+1 **

a) The way that they found that the relative frequency of rolling a 1 was by dividing the number of times that 1 occurred (11)

by the total number of times that they rolled the die (50): 11/50 = 0.22

To calculate the relative frequency of rolling a 4, divide the number of times that 4 occurred (9) by the total number of

times that they rolled the die (50): 9/50 = ????

b) First, find the relative frequency of rolling a 5: 12/50 = ????

and, then, multiply that answer by the number of times that you roll the die (3000): ?????

c) When a fair die is rolled, each number should come up as often as any of the other numbers; since there are 6 numbers

on a die, each number should come up about 1/6^{th} of the time.

To find the number of times that you expect a 5 to come up when you roll a die 3000 times, multiply (1/6) x 3000 = ?????

By the way, if you have only one, it is called a "die"; "die" is the singular, "dice" is the plural. You have 1 die or you

have 2 dice, or 3 dice, or ...
