Question 589092: find the probability that when three cards are dealt from a deck,you get one red followed by two blacks. Answer by John10(297) (Show Source):
You can put this solution on YOUR website! 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:)
