Question

the spinner is spun 75 times. what is the experimental probability of spinning the given result? round your answer to the nearest hundredth if necessary.

outcome	a	b	c	d

b or c
a. 0.33
b. 1
c. 0.67
d. 0.25

Explanation:

Step1: Find total frequency

Total spins = 75. Sum frequencies: \(20 + 11 + 14 + 30 = 75\) (checks out).

Step2: Find frequency of B or C

Frequency of B: 11, C: 14. So \(11 + 14 = 25\).

Step3: Calculate experimental probability

Probability = \(\frac{\text{Frequency of B or C}}{\text{Total trials}} = \frac{25}{75} = \frac{1}{3} \approx 0.33\).

Answer:

a. 0.33
