5.Probabilities are numbers on a scale between the numbers ___ and ___.

6.If P(A) = 31%, then P(not A) = ?

7.If P(A) = 0.5, and P(B) = 0.2, and if

P(A and B) =0.1, then find P(A or B)

8.IfP(A) = 0.5, and P(B) = 0.2, and ifA and B are independent events, find P(A and B)

9.IfP(A) = 0.5, and P(B) = 0.2, and if(B, given A has already occurred) = 0.1, find P(A and B)
