Step-by-step explanation:84% of a contractor's jobs involves electrical work. 75% of a contractor's jobs involve plumbing work. Of the jobs that involve plumbing, 90% of the jobs also involves electrical work. Let E = jobs involving electrical work L = jobs involving plumbing work Suppose one of the contractor's jobs is randomly selected. Using the sixth Excel worksheet, a) Find P (E). 0.84 b) Find P (L). 0.75 c) In words, what does E | L mean? d) Find P (E | L). e) Find P (E and L). f) Are E and L independent events? Why or why not? g) Find P (E or L). h) Are E and L mutually exclusive? Why or why not
