Alab is trying to determine if a new medication is effective at reducing acne breakouts. the results are displayed in the venn diagram below in the attachment:
what is the probability that the person's skin cleared up given that they used the medication?
a. 10%
b. 20%
c. 30%
d. 60%

D. 60%

Step-by-step explanation:

Let A = Event that person's skin cleared up

B= Event that person used the medication.

T be the total number of persons in this experiment.

From the Venn diagram , we have

n(A ∩ B) = 30

n (only A) = 10 and n(only B)=20

so , n(A)=n (only A) +n(A ∩ B) =10+30=40

n(B)=n(only B)+n(A ∩ B) =20+30=50

Now, the probability that the person's skin cleared up given that they used the medication :-

In percent , P(A|B)=60%

Hence, the probability that the person's skin cleared up given that they used the medication = 60%

Many people during this time, including Washington, felt that slavery was justified because the slaves in America were previously slaves in Africa, and were treated more poorly by their African masters than they were by their American masters. This was of course heavily refuted.
