Question

can you find probability of a if yiu have probability of b and probability of a intersect b

Answer 1

Answer #1

Answer)

Yes, probability of a, when b has already happened (P(A/B))

Is given by

P(A/B) = P(A intersect B)/(P(B)

It is written as,

P(A/B) = P(A and B)/P(B)

Where, P(A and B) is same as P(A intersect B).

From the textbook: Probability and Statistics for Engineering and the Sciences (9th Edition) Deer ticks can be carriers of either Lyme disease or human granulocytic ehrlichiosis (HGE). Based on a recent study, suppose that 16% of all ticks in a certain location carry Lyme disease, 10% carry HGE, and 10% of the ticks that carry at least one of these diseases in fact carry both of them. If a randomly selected tick is found to have carried HGE, what is...
