What does p(b/a) = 0.50 mean in terms of the venn diagram?

Other options C. is the correct answer

Of the 4 people who have a sister, 2 of these also have a brother.  

Step-by-step explanation:

P(B|A)=P(A∩B)P(A)

It is given that P(B|A)= 0.5

From the given ven diagram,

A consists of {Davis, Kari, Chu, Evan}

B consists of {Adam,Bucci,Lyle,Chu,Evan}

A ∩ B = {Chu,Evan}

Possible outcomes of A =4

possible out comes of B = 5

possible out comes A ∩ B = 2

P(B|A)=P(A∩B)P(A) = 2/4 = 1/2 =0.5

It means that, Of the 4 people who have a sister, 2 of these also have a brother.  

Other options C. is the correct answer

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
