Abel alonzo, director of human resources, is exploring employee absenteeism at the plano power plant. ten percent of all plant employees work in the finishing department; 20% of all plant employees are absent excessively; and 7% of all plant employees work in the finishing department and are absent excessively. a plant employee is selected randomly; f is the event "works in the finishing department; " and a is the event "is absent excessively." p(a ∪ f) =
(a) 0.07
(b) 0.10
(c) 0.20
(d) 0.13 (e) 0.17

0.23

Step-by-step explanation:

Given : F is the event "works in the finishing department;"

and A is the event "is absent excessively."

Given : 10% of all plant employees work in the finishing department; 20% of all plant employees are absent excessively; and 7% of all plant employees work in the finishing department and are absent excessively.

i.e. P(A)= 0.20 ;  P(F)=0.10 ; P(A ∩ F) = 0.07

We know that

Then,

Hence, the required answer is

i believe that the answer is

b. y-1=-2(x-4)

hope this !
