A die and a coin are tossed. Let A be the event that the die shows a 5 or a 6 and let B be the event that the coin shows heads.
A) Specify the sample space for the experiment
B) Specify the simple events in A, B, A union B, A intersection
B
C) Find the probability of A, B, A union B, A intersection B
D) Are A and B mutually exclusive? Are they independent?

(c)
P (A) = 1/6 + 1/6 = 2/6
P(B) = 1/2
P(AUB) = P(A) + P(B) = 2/6+1/2 = 5/6
P(A.int.B) = P(A) x P(B) = 2/6 x 1/2 = 1/6
(d) Mutually exclusive, did you not even attempt to think of the given scenario?

umm im good at math but im not sure this is right
well i think for D a and b are mutually exclusive...and independent...for C the probability of A is1/6 and b is also 1/6 and thats all im kinda sure of

the Idea of home work is for you to work it out and come up with the right answer... if some one else does it for you that is cheating... how will you work things out once your working for a company....
cheating is not the way to go about doing the job in hand... use your own brain,,, thats what you'll have to do later in life...

The probability is high that your teacher would prefer you to do your own homework. Approaching 100%, I would say.

Dude, we're not going to do your homework for you. You should have done it yourself.
