Just divide the top of the fraction by the bottom, and read off the answer!
Answer: The Answer Is C.
Step-by-step explanation:
When you divide each of them you will notice that C costs the least.
For choice A when you 5 by 3.25 you will get 0.65.
For choice B when you divide 8 by 6.10 you will get 0.7625
For choice C when you divide 12 by 7 you will get 0.5833.....
For choice D when you divide 10 by 6.44 you will get 0.644.
So when you look at the results you will see that choice C is the best deal.
Answer:
(a) P=0.694
(b) It is independent, beacuse the probability of having the disease for the children depends only on her mother condition (if she has the disease or not), not the condition of his brothers and sisters.
(c) P=0.25
Step-by-step explanation:
(a) If the mother has 0.33 probabilities of having the disease, the probability of the children having the disease is equal to the product of the probability of the mother having the disease (0.33) and the probability of inherit it (0.50).
So the probability of one child of having the disease is 0.33*0.5=0.167. The probability of not having the disease is then (1-0.167)=0.833
The probability of both children to not have the disease is 0.833^2=0.694.
(b) It is independent, beacuse the probability of having the disease for the children depends only on her mother condition (if she has the disease or not), not the ones of his brothers and sisters.
(c) If the mother has the disease, the child have a probability of 0.5 of having the disease.
The probability, given that the mother has the disease, of both child not having the disease is 0.5^2=0.25.
That is slope intercept form.
Slope intercept form is y=mx+b
