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

Open a book to any page
Look at the right-hand page
Record the page number
The list shows the results of Christine's experiment.

81, 209, 95, 203, 105, 389, 171, 367, 139, 159, 377, 121, 371, 107, 263, 297, 373, 387, 65, 319.

What is the experimental probability that Christine will randomly choose a page that is divisible by 3.

(Hint: a number is divisible by 3 if the sum of its digits is divisible by 3.)

Sagot :

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.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

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:

[tex]p = \frac{6}{20} = 0.3[/tex]

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