Question 589092
In a normal deck, we have 26 red cards and 26 black cards
The first red card is 26/52 or 1/2
The next black card is 26/51
The next black card is 25/50 or 1/2
Assume we can not replace the card back into the deck after took it out.

So the probability is: (1/2)*(26/51) *(1/2) = 26/204 or 13/102 = 0.127

Hope it helps:)
