Question

Example :

In rolling a die once , suppose that the event A is getting

an even number and the event B is getting a prime number and the event C is getting the five calculate the following probabilities :

1) P(A) , P(B) , P( C )

2) ??∪?, ??∩?, ? ?∩??, ???, ? (??P(A∪B), P(A∩B), P( A∩B^c ), P(A^c ), p (B^c)  

-------------------------

Example :

A coin is tossed three times , suppose that the event A is the heads is more

Than the tails come up and the event B is first toss results in tails .

Answer the following question :

1)Find the sample space by using tree diagram

2) Calculate

P(A) , P(B) ,??∪?, ??∩?, ?( ?∩??),P(A∪B), P(A∩B), P( A∩B^c) , ?(?)?〖p(A)〗^c

----------------------------------------------
