Answer:
2480 new movies
Step-by-step explanation:
1) First you need to find out how much money the 400 older movies made.
2) Next subtract that amount from the amount of revenue that the wants.
3) Divide the amount of leftover money by the amount that a new movie costs to rent
This means that in order to reach the desired amount of revenue the store must sell 2480 new movies.
As the question states,
John's brother has Galactosemia which states that his parents were both the carriers.
Therefore, the chances for the John to have the disease is = 2/3
Now,
Martha's great-grandmother also had the disease that means her children definitely carried the disease means probability of 1.
Now, one of those children married with a person.
So,
Probability for the child to have disease will be = 1/2
Now, again the child's child (Martha) probability for having the disease is = 1/2.
Therefore,
<u>The total probability for Martha's first child to be diagnosed with Galactosemia will be,</u>
(Here, we assumed that the child has the disease therefore, the probability was taken to be = 1/4.)
<em><u>Hence, the probability for the first child to have Galactosemia is </u></em>
