Question

Horses are housed in pasture, pipe pens or barn stalls at a local horse barn. Let A = {horse housed in barn stall}. Let the event B = {horse not housed in barn stall}: All of the answer choices are correct. B and A are mutually exclusive then B is the complement to A P(A or B) = P(A) + P(B) Horses are housed in pasture, pipe pens or barn stalls at a local horse barn. Let A = {horse housed in barn stall}. Let the event B = {horse not housed in barn stall}: All of the answer choices are correct. B and A are mutually exclusive then B is the complement to A P(A or B) = P(A) + P(B)

Explanation / Answer

All options are corrects. Becuase horse can be housed in a single placed. So event A and B are mutually exclusive. Since if a horse did not house in barn stall, horse housed in pipe pens or pasture so A and B are complement to each other. Since A and B mutually exclusive so

P(A and B)=0

So

P(A or B)=P(A)+P(B)
