-7 - 3x = 9x(x + 2)
Standard Form:
-9x^2 - 21x - 7 = 0
4.35 x 3 x 10^(-3) = 13.05 x 10^(-3) = 1.305 x 10^(-2)
Answer:
explained
Step-by-step explanation:
(i) Let A be the event that a student takes statistics subject as a major.
Let B be the event a student gets a job.
Two events (or propositions) are mutually exclusive or disjoint if they cannot both occur (be true). A clear example is the set of outcomes of a single coin toss, which can result in either heads or tails, but not both.
In this case, the event A and B are not mutually exclusive.
Therefore, P(A or B) = P(A U B) = P(A) + P(B) − P(A ∩ B)
