Answer:
the probability of having sickle cell anemia given that you are African-American is P( B|A) =0.288
Step-by-step explanation:
Using Bayes's theorem
P( B|A) = P( A∩B)/P(A)
where P( B|A) = probability of the event B knowing that A happened , P( A∩B) = probability that A and B happen (joint probability of A and B) , P(A) = probability of event A
if B= probability of having sickle cell anemia and A= probability of being African-American
then
P( A∩B) = 0.13
P(A) = 0.45
then
P( B|A) = P( A∩B)/P(A) = 0.13/0.45 = 0.288
P( B|A) =0.288
Answer:
3) The number of apples at the start
Given that sandwiches are made with either turkey or ham.
Prob for turkey or ham = 1/2
The fruit can be either apple or orange. Hence p(apple) = p(orange) =12
Drinks can be either bottled water or juice
P(water) = P(juice) = 1/2
We find that sandwiches, fruits, and drinks are mutually independent of each other.
Hence the probability you will get an orange and not get juice in your box
Prob (you get an orange and bottled water)
= Prob (orange) *Prob (bottled water) (since the two are independent
= 1/2 (1/2)= 1/4
Hence answer is 0.25
