I have exams coming up and I have a question say hypothetically you have a 71.69% as a grade and you fail your exam which is 10% of you’re grade what would be you’re over all score. Also could you also tell me what it would be if the exam is 20% if you’re grade?

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18}, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.
