You can put this solution on YOUR website! THERE ARE 26 RED CARDS OUT OF 52.
HENCE PROBABILITY OF DRAWING RED CARD FIRST=26/52=1/2
NOW THERE ARE 26 BLACK CARDS AND 51 TOTAL CARDS
PROBABILITY OF DRAWING BLACK CARD IS =26/51
SO PROBABILITY OF DRAWING FIRST RED AND THEN BLACK CARD =(1/2)(26/51)
THIS ENDS YOUR PROBLEM.
*****************************************************************************
BUT IF PROBILITY OF ONE RED AND ONE BLACK CARD IS NEEDED THEN.....
SIMILARLY PROBABILITY OF DRAWING FIRST BLACK AND THEN RED CARD =(1/2)(26/51)
HENCE TOTAL PROBABILITY OF DRAWING ONE BLACK AND ONE RED CARD =SUM OF THE ABOVE 2 PROBABILITIES.=26/51
