There are 3 face cards for each : spade, club, diamond, hearts
When the three face card of heart are removed, we lost :
(i) 3 red cards out of 26
(ii) 3 face cards out of 12
(iii) 3 hearts out of 13
(iv) 3 cards out of 52 in total
Now, coming back to question,
(a) P(red face card) = 3 / 49
(b) P(black face card) = 6/49
(c) P(red card) = 23/49
(d) P(black card) = 26/49
