Events a and b are overlapping. p(a) = 4/11 ; p(b) = 3/11 , p(a and b) = 2/11 . find p(a or b).

We know that:

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

so:

P(A or B) = 4/11 + 3/11 - 2/11 = (4+3-2)/11 = 5/11

c is the final answer! : )

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
