Maryann is testing the effectiveness of a new acne medication. there are 100 people with acne in the study. fifty-five patients received the acne medication, and 45 other patients did not receive treatment. thirty of the patients who received the medication reported clearer skin at the end of the study. twenty-two of the patients who did not receive medication reported clearer skin at the end of the study. what is the probability that a patient chosen at random from this study took the medication, given that they reported clearer skin?

0.58

Step-by-step explanation:

Let A = Event that the patients received the acne medication.

B = Event that the patients did not receive the acne medication.

C = Patient reported  reported clearer skin.

Now,

Using Bayes theorem, The probability that a patient chosen at random from this study took the medication, given that they reported clearer skin:

Hence, the required probability : 0.58

the monthly balance will be $75,000

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
