Question

Dean has a spinner that is divided into 4 equal sections are labeled 1, 2, 3, and 4. Dean spun the spinner 60 times. He recorded the results.
1=12
2=17
3=15
4=16
Which of the following are experimental probabilities from the table? Select two answers.

A.

15
B.

17/60

C.

14

D.

7/15

E.

12/43

Answer 1

Answer:

B

Step-by-step explanation:

Dean recorded the results of spinning the spinner 60 times:

• Number  1 spun 12 times
• Number  2 spun 17 times
• Number  3 spun 15 times
• Number  4 spun 16 times

The experimental probability is the ratio of the number of times an event occurs to the total number of trials or times the activity is performed.

Find all experimental probabilities:

$P_{1}=\dfrac{12}{60}=\dfrac{1}{5}\\ \\P_{2}=\dfrac{17}{60}\\ \\P_3=\dfrac{15}{60}=\dfrac{1}{4}\\ \\P_4=\dfrac{16}{60}=\dfrac{4}{15}$

Hence, option B is correct
