Suppose a and b are independent . if p(a) = 0.7 and p(b) = 0.8 , what is p(aωb)

Given events A and B are mutually inclusive...P(A or B) if P(A) = 0.4                  P(B) = 0.7                  P(AΩB) = 0.3I know I have to use the addition rule and the fomulanecessary is P(A or B) = P(A)+P(B)-P(AΩB)I am using the greek symbol as intersection not even sure ifit is appropriate to use that symbol as intersection.Do I just plug the numbers in and get 0.8 as myprobability?

step-by-step explanation:

yes it is1. move over 2 points on the x-axis2. move over 2 points on the y-axis

put like terms together.orremember that the 45 becomes negative when moved to the other side.orthe minuses cancel out.
