Question

the spinner below was spun 25 times and the results are as follow: red: 9 times ; blue: 2 times ; yellow: 11 times ; 3 brown. what is the experimental probability that the spinner lands on brown? a) 0/10 b) 3/25 c) 1/25 d) 1/10

Explanation:

Step1: Recall experimental - probability formula

Experimental probability \(P(E)=\frac{\text{Number of times event occurs}}{\text{Total number of trials}}\)

Step2: Identify values

The number of times the spinner lands on brown is 3, and the total number of spins is 25.

Step3: Calculate probability

\(P(\text{brown})=\frac{3}{25}\)

Answer:

B. 3/25
