Human blood may contain either or both of two antigens, AandB. Blood that containsonly theAantigen is called typeA, blood that contains only theBantigen is called typeB, blood that contains both antigen is called typeAB, and blood that contains neitherantigen is called typeO. At a certain blood bank, 35% of the blood donors have typeAblood, 10% have typeB, and 5% have typeAB.(a) What is the probability that a randomly chosen blood donor is typeO

The probability of blood group O is P(O) = 0.50

Step-by-step explanation:

P(A)   = 35/100

P(B)   = 10/100

P(AB) = 5/100

P(O)   = ?

P(O) = 1 - ( P(A)+P(B) + P(AB))

        = 1 - (35/100 + 10/100 + 5/100)

        = 1 - 50/100

       P(O)   = 0.50

s + (a + 178) = 2000

step-by-step explanation:

2000 - 178 = 1822

1822 / 2 = 911

911 + 178 = 1089

1089 + 911 = 2000

abha = 1089

shane = 911

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.
