Box A contains five
four
white marbles and six
black marbles. Box B contains seven
white marbles and
black marbles. An experiment consists of first selecting a marble at random from Box A. The
marble is transferred to Box B and then a second marble is drawn from Box B. What is the
probability that the first marble was white given that the second marble was white? (Round your
answer to three decimal places.)
Title : Feb 10-12:36 PM (Page 1 of 2)
If A and B are independent events, P(A) = 0.15
, and P(B) = 0.75
(a) P ( A ∩ B )
(b) P ( A ∪ B )
(c) P ( A | B )
(d) P ( A c ∪ B c )
