value: 3\na magazine contains twelve pages. you open to a random page. what is the probability that the page number is nine or eleven?\n\na. 1/144\nb. 1/6\nc. 1/12\nd. 9/11

Answer

Explanation:

Step1: Determine total outcomes

The magazine has 12 pages, so total number of possible outcomes is 12.

Step2: Determine favorable outcomes

The favorable outcomes are page number 9 or 11, so there are 2 favorable outcomes.

Step3: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P = \frac{2}{12}=\frac{1}{6}$.

Answer:

B. 1/6
