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.

masha68 [24]

Answer:

<h2>Direction is represented by +9, indicating that is moving in a positive direction (upwards).</h2><h2>Zero is the reference point.</h2>

Step-by-step explanation:

So, basically, we need to apply a reference system to express directions, because all movements are represented respect to a reference point. In this case, number zero represents that reference point, which is located in the ground, setting this reference point we can measure the distance that Xavier traveled upwards the apple tree.
