Example 3.15 from Statistics, 3.3 Two Basic Rules of Probability
c. Are A and B independent?
Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.
c. No, they are not, because P(B AND A) = .585.
P(B)P(A) = (.65)(.65) = .423
.423 ≠ .585 = P(B AND A)
So, P(B AND A) is not equal to P(B)P(A).
How did it go?
