The proportions of blood phenotypes, A, B, AB, and O, in the population of all Caucasians in the United States are approximately

Vanyuwa [196]

Answer:

a. S = {A,B,AB,O}

b. P(A) = 0.41, P(B) = 0.1, P(AB) = 0.04, P(O) = 0.45

c. 0.45 = 45% probability that the person chosen at random has either type A or type AB blood

Step-by-step explanation:

a List the sample space for this experiment.

All possible blood types(A, B, AB or O). So

S = {A,B,AB,O}

b Make use of the information given above to assign probabilities to each of the simple events.

The proportions of blood phenotypes, A, B, AB, and O, in the population of all Caucasians in the United States are approximately .41, .10, .04, and .45, respectively.

P(A) = 0.41, P(B) = 0.1, P(AB) = 0.04, P(O) = 0.45

c What is the probability that the person chosen at random has either type A or type AB blood

P(A) + P(AB) = 0.41 + 0.04 = 0.45

0.45 = 45% probability that the person chosen at random has either type A or type AB blood

Please help!!!

Answer:

Just be yourself. Also, in most cases, it's helpful to just let the boy come to you. If he comes to you and says he likes you, you should also express your own feelings. ALWAYS be yourself. If you aren't yourself, the relationship will not work out. The boy should like you for who you are, not who you're trying or pretending to be.

Jason poured 1 gallon 1 quart of water into an empty 2-gallon bucket. How much more water can be added to reach the bucket's 2-g

Romashka [77]

Answer: 3 quart

Step-by-step explanation:

Given

Jason poured 1 gallon 1 quart of water into an empty 2 gallon bucket

1 gallon can be written as 4 quart

So, 2 gallon can be written as 8 quart

Subtract 1 gallon 1 quart(5 quart) from 2 gallon(8 quart) to get the volume added

$\Rightarrow 8-5\\\Rightarrow 3\ \text{quart}$

So, 3 quart of water must be added to reach 2 gallon capacity.

Item 3 Question 1 A teacher spends $354 on costumes and microphones for six cast members in a play. Each cast member receives a

vovikov84 [41]

The microphone was $126.

You would multiply $38 by 6 which equals $228.

Then do $354-$228 which equals $126.

Whats 1/5 - 1/7 please can you tell me how to work it out<br> thanks

Andrej [43]

Convert the fractions so they both have the same denominator (bottom part of the fraction)

1/5 = 7/35

This is because 5*7=35, so 1*7=7

1/7 = 5/35

This is because 7*5=35, so 1*5 =5

Then subtract the top numbers to get the answer:

$\frac{7}{35}-\frac{5}{35} = \frac{2}{35}$
