use the spinner below. what is the probability of the spinner landing on 4 or 5? p(4 or 5) = question help: message instructor
Answer
Explanation:
Step1: Identify total outcomes
The spinner has 12 equal - sized sections, so the total number of possible outcomes is $n = 12$.
Step2: Identify favorable outcomes
The favorable outcomes are the spinner landing on 4 or 5. There are 2 favorable outcomes, so $m=2$.
Step3: Calculate probability
The probability formula is $P(A)=\frac{m}{n}$. Substituting $m = 2$ and $n = 12$, we get $P(4\text{ or }5)=\frac{2}{12}=\frac{1}{6}$.
Answer:
$\frac{1}{6}$
