Question

finding relative frequency
a number cube is rolled 60 times. the results of those 60 trials are recorded in the table. complete the table.
a=
b=

number rolled observed frequency relative frequency
1 10 1/6
2 12 a
3 10 1/6
4 10 1/6
5 8 b
6 10 1/6

Explanation:

Step1: Recall relative - frequency formula

Relative frequency = $\frac{\text{Observed Frequency}}{\text{Total Number of Trials}}$

Step2: Calculate value of A

The observed frequency of rolling a 2 is 12, and the total number of trials is 60. So, $A=\frac{12}{60}=\frac{1}{5}$

Step3: Calculate value of B

The observed frequency of rolling a 5 is 8, and the total number of trials is 60. So, $B = \frac{8}{60}=\frac{2}{15}$

Answer:

A. 1/5
B. 2/15
