I'm pretty sure that that
P(Ei) = ? / k^n
The sample space is k*k*k*k n-times.
But i don't see how to count not getting the jth player.
Hi,
Assume hat every time you buy a box of Corn Flakes, you receive one of the pictures of the k players of the Florida Marlins. Over a period of time you buy n >= k boxes of Corn Flakes. Let Ej, j=1,2,3,...,k, denote the event you do not get the jth player's picture.
What is the probability of Ej?
What is the probability of Ej intersect Ei (i is just another player)?
Thanks,
I think once i have those I can use the inclusion-exclusion principle to answer what is the even you do not get at least one picture.
I think that you both need to rethink this problem.
Suppose you toss a die ten times. What is the probability of not getting a two?
In the problem if k=6 then what is the probability of not getting player b in ten boxes?
Toss a die ten times; what is the probability of getting neither a two nor a three?
If k=6 then in buying 10 boxes what is the probability of getting neither player b nor player c?
Toss a die ten times; what is the probability of getting none of 2, 3 or 4?
If k=6 then in buying 10 boxes what is the probability of getting none of player b, player c or player d?
