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

Answer:
Probability that a student chosen randomly from the class plays basketball or baseball is or 0.76
Step-by-step explanation:
Given:
Total number of students in the class = 30
Number of students who plays basket ball = 19
Number of students who plays base ball = 12
Number of students who plays base both the games = 8
To find:
Probability that a student chosen randomly from the class plays basketball or baseball=?
Solution:
---------------(1)
where
P(A) = Probability of choosing a student playing basket ball
P(B) = Probability of choosing a student playing base ball
P(A \cap B) = Probability of choosing a student playing both the games
<u>Finding P(A)</u>
P(A) =
P(A) = --------------------------(2)
<u>Finding P(B)</u>
P(B) =
P(B) = ---------------------------(3)
<u>Finding </u>
P(A) =
P(A) = -----------------------------(4)
Now substituting (2), (3) , (4) in (1), we get
To find expanded form, we need to split up the digits. When you do that, you take one digit and cut off everything to the left of it, then make everything to the right zeros.
We don't need to keep the zeros.
We can check this by adding the numbers back up to get .
