A card is selected from a deck. Find the following probabilities.

A standard deck of cards has 52 Cards. There are 13 values and 4 suits. Suits are Spades, Clubs, Diamonds and Hearts. Each suit has 13 cards. There are 3 face cards Jack, Queen, and King.

a red card = 26/52 = 1/2
a face card = 12/52 = 3/13
a jack and a spade = 4/52 jack, 13/51 spade = 52/2652 = 1/51

Is this correct!

Almost.
red card=26/52=1/2
face card=12/52=3/13
jack and spade=4/52 x 12/51 (Subtracting the jack of spades)=48/2652=4/221
