Question

You have a standard deck of cards. You pick a card, put it back, and then pick a second card. What is the probability you will get two red cards?

Answer 1

Answer: 25%

Step-by-step explanation:

There are 52 cards in a deck. Half of them are red and half of them are black, so there is a 50% or 1/2 probability you will choose a red card at first. You put the card back, so the second time there is still a 50% or 1/2 probability you will pick a red card. You would then multiply theses two probabilities together.

1/2x1/2=1/4

1/4 is also 25%
