Can anyone please guide me in solving the following problem:

*Suppose I have a well shuffled stantard deck of 52 cards and I divide the deck into two halves (each half containing 26 cards) and keep the first half aside. Now, from the first half, I pick a card at random. What is the probability that my chosen card is a queen?*

I am not picking up a card from a deck of 52 cards. I divide the deck into two. I don't know how many Queens went into my half. So, how do I account for that?

Dividing in half doesn't do anything since you do not know which cards are in the second half.

giventhe number of Queens in the half deck; that is quite simple. However, the problem I am facing is calculating the probability of the number of Queens entering my half deck.Log in to reply

Does splitting the deck of cards into half add/subtract anything from the information available to you?

When you figure that out, try this
