1 answer:
Answer:
(A) n(Eᶜ)=40
Step-by-step explanation:
The Sample Space for is given as:
(1,2),(1,3),(1,4),(1,5),(1,6),(1,7),(1,8),(1,9),(1,10),(1,11)
(2,3),(2,4),(2,5),(2,6),(2,7),(2,8),(2,9),(2,10),(2,11)
(3,4),(3,5),(3,6),(3,7),(3,8),(3,9),(3,10),(3,11)
(4,5),(4,6),(4,7),(4,8),(4,9),(4,10),(4,11)
(5,6),(5,7),(5,8),(5,9),(5,10),(5,11)
(6,7),(6,8),(6,9),(6,10),(6,11)
(7,8),(7,9),(7,10),(7,11)
(8,9),(8,10),(8,11)
(9,10),(9,11)
(10,11)
n(S)=55
Event E is the Event that the two numbers are odd.
Therefore: Complement of E will be the event that any of the two numbers is even.
The Sample Space of the complement of E is:
Therefore:
n(Eᶜ)=40
