Answer:
There are 128 outcomes in the complement of E
Step-by-step explanation:
Given that a bag contains 12 balls numbered from 1 to 12. Two balls are selected from the bag one at a time, without replacement. (order matters)
Possibilities of getting sum of 5 is drawing in this order
(1,4) (2,3) (3,2) (4,1) = 4 ways
Total no of ways of drawing 2 balls from 12 balls where order matters
= 12P2
= 132
Thus we have
n(E) = 4
n(sample space ) =132
Hence
n(E') = [tex]132-4=128[/tex]
There are 128 outcomes in the complement of E
