Answer: no -10 isn't a rational number
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.
