<PRE><B>Question 1102041</B>
 A lot contaning six items is comprised of four good items and two defective items.two items are selected at random from the lot for testing purposes.
a)list the simple events for this experiment.
gg ; dd ; gd ; dg
-----------------------
b)list the simple events in each of the three following events:
A:at least one item is defective. gd ; dg ; dd
---------------------------------------------
B:exactly one item is defective. gd ; dg
-------------------------
C:find P(A),P(B) and P(C) by using the simple events approach
P(A) = 1 - P(gg) = 1 - 4C2/6C2 = 1 - 6/15 = 3/5
-----------
P(B) = 2/6C2 = 2/15
---------------------------
