Question

4.2 theoretical probability. calculating theoretical probabilities (other). use the spinner below. what is the probability of the spinner landing on 3? p(3) = question help: video message instructor

Explanation:

Step1: Identify total outcomes

The spinner is divided into 12 equal - sized sections. So the total number of possible outcomes when spinning the spinner is $n = 12$.

Step2: Identify favorable outcomes

The number of sections labeled '3' is $m=1$.

Step3: Use probability formula

The probability formula is $P(A)=\frac{m}{n}$, where $A$ is the event of the spinner landing on 3. Substituting $m = 1$ and $n = 12$ into the formula, we get $P(3)=\frac{1}{12}$.

Answer:

$\frac{1}{12}$
