Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Olivia and Cody both have spinners with the color purple. Olivia determines that the probability of spinning purple on her spinner is 4 out of 12. Cody determines that the probability of spinning purple on his spinner is 3 out of 10. Which of the following statements is true?
A
Olivia’s spinner has the highest probability of spinning purple.
B
Cody’s spinner has the highest probability of spinning purple.
C
Both spinners have equal probabilities of spinning purple
D
There is not enough data to determine which spinner has the highest probability of spinning purple.
Explanation: 

Detailed explanation-1: -This probability is equal to the amount of ‘1’s divided by the total amount of numbers on the spinner. There are 8 numbers in total on the spinner. There are 3 ones on the spinner. The probability of spinning a ‘1’ is 3 / 8 .

Detailed explanation-2: -The chances of landing on red are 1 in 4, or one fourth. This problem asked us to find some probabilities involving a spinner. Let’s look at some definitions and examples from the problem above.

Detailed explanation-3: -What are the chances of landing on blue after spinning the spinner? What are the chances of landing on red? Solution: The chances of landing on blue are 1 in 4, or one fourth. The chances of landing on red are 1 in 4, or one fourth.

Detailed explanation-4: -The answer is the experimental probability of the spinner landing on yellow is 28% of the time.
