Question

use the spinner below to find the probability of getting the following after 1 spin. p(9 or 6) = (round to 4 decimal places)

Explanation:

Step1: Determine total outcomes

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

Step2: Determine favorable outcomes

The event of getting a 9 or a 6 has 2 favorable outcomes, so $n(E)=2$.

Step3: Calculate probability

The probability formula is $P(E)=\frac{n(E)}{n(S)}$. Substituting the values, we get $P(9\text{ or }6)=\frac{2}{12}=\frac{1}{6}\approx0.1667$.

Answer:

$0.1667$
