Christine performed the following experiment 20 times using a book that contains 462 pages.

wel

Using the probability concept, it is found that there is a 0.3 = 30% experimental probability that Christine will randomly choose a page that is divisible by 3.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In an experimental probability, these number of outcomes are taken from previous trials.

In this problem:

The experiment was made 20 times.

Of those, in 6 experiments(81, 105, 171, 159, 297, 387) she choose a page that was divisible by 3.

Then:

$p = \frac{6}{20} = 0.3$

0.3 = 30% experimental probability that Christine will randomly choose a page that is divisible by 3.

N76 [4]

Permutation helps us to know the number of ways an object can be arranged in a particular manner. The correct option is D.

<h3>What are Permutation and Combination?</h3>

Permutation helps us to know the number of ways an object can be arranged in a particular manner. A permutation is denoted by 'P'.

The combination helps us to know the number of ways an object can be arranged without a particular manner. A combination is denoted by 'C'.

The example which is an example of permutation is Selecting a first-, second-, and third-place winner at baking.

Hence, the correct option is D.
