Question

During an experiment, Juan rolled a six-sided number cube 18 times. The number two occurred four times. Juan claimed the experimental probability of rolling a two was approximately 1/9. Which of the following is true about Juan’s claim?

A. Juan’s claim is incorrect. The correct experimental probability is 2/9.
B. Juan’s claim is incorrect. The correct experimental probability is 1/3.
C. Juan’s claim is incorrect. The correct experimental probability is 4/9.
D. Juan’s claim is correct.
PLEASE HURRY!!!!!!!!!!
God bless, stay safe, and happy holidays! :)

Answer 1

Answer: (A) Juan's claim is incorrect. The correct experimental probability is 2/9

Step-by-step explanation:

This is because when Juan rolled the dice 18 times the number 2 was rolled 4 times. The probability would be 4/18, which when simplified would be 2/9.

Hope this helps!!

Answer 2

The experimental probability can be calculated by dividing the number of favorable outcomes by the total number of trials. Given Juan rolled the number two a total of four times, the experimental probability would be 4 ÷ 18, or 4/18. When we simplify this fraction, we will find the answer to be 2/9. Because this does not align with Juan's initial statement, Juan is incorrect. The correct experimental probability is 2/9, meaning option A is the only accurate choice.
