Question

Marco draws a card and replaces it 10 times from a standard deck of 52 cards. He draws 8 red cards and 2 black cards. What is the theoretical probability that he will draw a red card on his 11th draw?

Answer 1

4/5 chance is the answer to that

Answer 2

The probability would be 1/2 that he would draw a red color card.

Explanation:

Marco draws a card from a standard deck of 52 cards and replace it 10 times. each time Marco draws 'with replacement' so it does not matter what cards were drawn previously so each draw result was independent.

In a standard deck of 52 cards there are 26 red cards.

p (drawing a red card on his 11th draw) = 26/52 = 1/2

therefore on his 11th draw 1/2 probability that he would draw a red color card
