Answer:
Mid-Atlantic Ridge Theory
Step-by-step explanation:
hope this helps. :)
The sample space of an experiment is changed when some additional information pertaining to the outcome of the experiment is received. The effect of such information is to <u><em>reduce</em></u><em> </em>the sample space by excluding some outcomes as being impossible which before receiving the information were believed possible . The probabilities associated with such a <u><em>reduced</em></u> sample space are called conditional probabilities.
<u><em>Knowing a student’s grade level does not help determine if he or she uses social media.</em></u>
<u><em /></u>
The given survey explains the conditional probability.
The students of the<u><em> reduced</em></u> sample space i.e. of 9th grade have the probability of 81% who use the social media.
The students of 8th grade that use social media can be greater or less than 81%.
Therefore this experiment <u><em>does not</em></u> help determine if he or she uses social media on the basis of his/her grade.
Only the <u><em>last option </em></u>is correct.
The conditional probability can be understood by the following.

There can only be less than or equal to 125 customers, you can't have more than that but you can have exactly 125 or less than 125. your inequality should look like < 125 with a line underneath the symbol to describe "equal to"
What do you mean? That question doesn't make sense.
