Question

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

Explanation:

Step1: Calculate total number of trials

Total trials \( N=10 + 8+10 + 10+12 + 10=60\)

Step2: Calculate relative frequency \(A\)

Relative frequency \(A=\frac{\text{Observed frequency of }2}{\text{Total trials}}=\frac{12}{60}=\frac{1}{5} = 0.2\)

Step3: Calculate relative frequency \(B\)

Relative frequency \(B=\frac{\text{Observed frequency of }5}{\text{Total trials}}=\frac{8}{60}=\frac{2}{15}\approx0.13\)

Answer:

\(A = 0.2\), \(B=\frac{2}{15}\)
