this is for a weekly form post in statistics.

"Finding a conditional Probability:

Example

Let's look at a standard deck of 52 cards.

What is the probability of getting 2 kings assuming that the first one is not replaced?

4/52 * 3/51 = 1/13*1/17= 1/221

What is the probability of getting 2 kings assuming that the first one is replaced?

4/52 * 4/52 = 1/13 * 1/13 = 1/169

Instructions

Now for your main post complete similar problem using with replacement and without replacement. You can use a card problem as long as it is not 2 kings. Try your best to be original. Do not solve your own problems. Leave them for your classmates to work.

For your response pick 2 classmates.On each post copy their problem, then show your work explaining how you worked each problem, and then show your answer. Of course there will be more than one comment on each person's work. Stay positive when replying."

next is the post i am requesting help with.

Assume you have 3 decks of cards that are combined.

What is the probability of getting 5 (6)'s assuming that they are not replaced?

What is the probability of getting a 6 of diamonds and a 4 of diamonds?
