In addition to the blood types A, B, AB , and O, a person’s blood may be classified as Rh positive or Rh negative. In the United
VARVARA [1.3K]

Answer:

D. Assign the integers 00 through 84 to people with Rh positive blood and the integers 85 through 99 to people with Rh negative blood.

Step-by-step explanation:

If you want to simulate a percentage, you need to have 100 possible events. If you use 1-100, the range will be 1-85 for positive and 86-100 for negative. Looking at the option its all using 99 as the ceiling, so we use 0-99. Since we use 0, then you have to subtract 1 on the number range. There are 85% chance of Rh-positive, so the assigned number will be  

1 through 85

(1-1) through (85-1)

0 through 84

The range for Rh-negative will be:

86 through 100

86-1 through  100-1

85 through 99

Option B is wrong because it assigns 00 through 84 to people with Rh negative blood, not Rh-positive. The right answer will be option D.

As we can see the grouped factoring is not all negative...

Thus, your answer.
