Question

chapter 3: 3.1 probability terminology (concepts, simple, complements) score: 6/12 answered: 6/12 progress saved done question 8 use the spinner below to find the probability of getting the following after 1 spin. p(10 or 12) = (round to 4 decimal places)

Explanation:

Step1: Identify total outcomes

The spinner has 12 equal - sized sections, so the total number of possible outcomes $n(S)=12$.

Step2: Identify favorable outcomes

The event is getting a 10 or 12. The number of favorable outcomes $n(E)=2$ (the sections labeled 10 and 12).

Step3: Calculate probability

The probability formula is $P(E)=\frac{n(E)}{n(S)}$. Substituting the values, we get $P(10\text{ or }12)=\frac{2}{12}=\frac{1}{6}\approx0.1667$.

Answer:

$0.1667$
