Question

A person with type A blood can donate red blood cells to people
with type A or type AB blood. About 31% of the US population has
type A blood. University High held a blood drive where 50 students
donated blood. What is the probability that at
* least* 17 of the students had type A
blood?

Answer #1

The percentage of whole blood occupied by red blood
cells is called the
platelet count
Hematocrit
hemoglobin content
Differential
Red blood cells contain:
Hemoglobin
Myoglobin
Albumin
Globulin
A person with blood type A has
B antigens on the RBC
no antigens on the RBC
A antibodies
A antigens on the RBC
An individual with __________ blood can theoretically
donate blood to recipients of all ABO types
A
O
B
AB
A person with blood type ___ is a universal recipient...

a)The probability that a person has blood type A is .30. The Red
Cross selects two persons at random. Find the probability that the
first person has blood type A and the second person does not have
blood type A.
b) The probability that a person drinks at least five cups of
coffee a day is .25, and the probability that a person has a high
blood pressure is .10. Assuming that these two events are
independent, find the probability...

Knowing your blood type is important not only because it
determines who you can donate blood to but also who you can receive
blood from. The second most common blood type in Canada is A
positive and 36 percent of Canadians share this blood type.
The least common blood type is AB negative and only 0.5
percent of Canadians have this blood type. Suppose a random sample
of 100 Canadian donors has been chosen at random. In this sample,
let...

6. Suppose that 4% of people have AB+ blood type. How many
people need to be sampled so that there is more than a 50% chance
that at least one person in the group has type AB+ type?

Among a group of people, the blood type AB- is found, on
average, 1 person in 100 people. If you randomly select 200 people
from this group, what is the probability to find more than 3 people
with AB- type blood ?
Find solution by
A.using the Binomial distribution and also
B. by the Poisson distribution.
You must write down both the respective formulas and evaluate
them numerically.

The American Red Cross says that about 45% of the U.S.
population has Type O blood, 40% Type A, 11% Type B, and 4% Type
AB. Suppose we select 5 blood donors at random.
What is the probability that the fifth donor is the first donor
with Type O blood?
What is the probability exactly two of the five donors will
have Type O blood?
What is the probability none of the five donors will have Type
O blood?
What...

Let’s say that about 38% of the population has O+ blood type.
If we had 217 volunteers come in to donate blood, about how many
would we expect to have O+ blood? Say we needed to get 100 people
with O+ blood to meet current demand. What is the probability that
we will reach that goal with the 217 that came? How could we
increase the probability of getting at least 100 with O+ to
donate?

45% of people have type O blood . If 400 volunteers show
up to donate blo, use the Normal approximation to the binomial to
find the probability that more than 175 but at most 182 have type O
blood.

1. If a person that has blood type O has a child with a person
that has blood type AB, what is the probability that the child will
be blood type A?
a.
0%
b.
25%
c.
50%
d.
75%
e.
100%
2. Red-green color blindness is inherited through an
X-linked, recessive allele (b).
Two parents, Fred and Ginger, have normal vision. They have two
daughters, Takiyah and Kelly, who also have normal vision, and a
color-blind son, David. What...

In a group of 1000 people, only 2% have Type AB blood.
a) On average, how many donors must be checked to find someone
with Type AB blood?
b) What's the probability that there is a Type AB donor among
the first 3 people checked?
c) What's the probability that the first Type AB donor will be
found among the first 6 people?
d) What's the probability that there won't be a Type AB donor
before the 10th person?
