Let P(A) = 0.45, P(B | A) = 0.30, and P(B | Ac) = 0.06. Use a probability tree to calculate the following probabilities: (Round your answers to 3 decimal places.) a. P(Ac) b-1. P(A ∩ B) b-2. P(Ac ∩ B) c. P(B) d. P(A | B)

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
