Question

A'zariah spins the spinner a total of 30 times. It lands on C 8 times, & it lands on B 5 times. What is the experimental probability of landing on C OR B?

A. 8/30
B. 5/30
C. 13/30
D. 83%

Answer 1

To find the experimental probability of landing on either C or B, we need to calculate the total number of times it landed on C or B and then divide that by the total number of spins.

A'zariah spun the spinner 30 times. The results are:
- Landed on C: 8 times
- Landed on B: 5 times

Now, we add the number of times it landed on C and B:
\[
\text{Total for C or B} = 8 + 5 = 13
\]

Next, we calculate the experimental probability by dividing the total times it landed on C or B by the total spins:
\[
\text{Probability of landing on C or B} = \frac{13}{30}
\]

Thus, the experimental probability of landing on C or B is \( \frac{13}{30} \).

The correct answer is:
**C. \( \frac{13}{30} \)**
