The probability for event A is 0.3, the probability for event B is 0.6, and the probability of events A or B is 0.8. Why are the

events not mutually exclusive? The sum of P(A) and P(B) is less than P(A or B). The product of P(A) and P(B) is less than P(A or B). The product of P(A) and P(B) is not equal to P(A or B). The sum of P(A) and P(B) is not equal to P(A or B).

Llana [10]
Q = 3s - 9/6
q = 3(s - 3)/6
q = s - 3/2

What are the steps to construct parallel lines using a compass and straightedge?

Tju [1.3M]
Just match the angles and sides. Rotate the shape on your head.

If you are smart enough to use a smart phone then trust me this is peanuts for YOU !
