The spinner

The spinner below is spun 12 times. It landed on I 4 times, II 7 times, and III 1 time. What is the difference between the experimental and theoretical probabilities of landing on the II?

Final Answer:

d =  0.25

Step-by-step explanation:

$$\begin{gathered} p_1=\frac{7}{12}\doteq 0.5833 \\ {p}_2=\frac{1}{3}\doteq 0.3333 \\ d=p_1-p_2=\frac{7}{12}-\frac{1}{3}=\frac{7}{12}-\frac{4}{12}=\frac{7-4}{12}=\frac{3}{12}=\frac{1}{4}=0.25 \end{gathered}$$
