Question

tree diagram , any one great with these?

please standby while I attach the problem

Answer 1

\[P(A|D)=x× r\]

Answer 2

it didn't work :(

Answer 3

oh, i was reading the notation incorrectly,

P(A|D) means the probability that A occurs , given that D occurs

Answer 4

how do I do that do I have to multiply by 100??

Answer 5

there are two cases that D occurs y-B-t-D

and x-A-r-D


we know D has occurred,
the only thing we aren't sure about is as it through x or y?

Answer 6

to get A it must have been through the x branch, what is the probability of this ?

Answer 7

i think it's just \(x\)
