Answer 2

so, in additivity

Answer 3

mutually exclusive means that Event A is independent of Event B

Answer 5

3mar posted a jpeg about probability i'm just trying to go through it

Answer 6

so I would add the probabilities of two events if they are independent of eachother. so that would be the probability of both those events happening.

p(A)+p(B)

Answer 7

Am I thinking about this correctly @3mar

Answer 8

event A is independent of event B. so the sum of their probabilities is the probability that either A or B happens but not both simultaneously, but the can't occur simultaneously because their is no dependence on eachother

Answer 9

It is not a shame when I say I am not so good at probability.
