Question

if I choose two cards, one of the time, from a standard deck of cards, what’s my probability that I choose A red card, then without putting it back to a black card

Answer 1

P(Red) = 26/52, P(Black) = 26/51

Explanation:

There are 26 red cards and 26 black cards in a standard deck of 52 cards.

This means the probability of picking a red card from the deck is 26/52.

Now, since we are taking out the red card after drawing from the deck, we only have 51 cards. Therefore, the probability of picking a black card from the deck is 26/51.
