Solution

1.

The probability that it is a red card.

Total number of red cards (required outcomes)= 26

Total number of cards or sample space = 52


The\text{ probability that it is a red card = }(26)/(52)\text{ = }(1)/(2)

2)

Total number of face cards (required outcomes)= 12

Total number of cards or sample space = 52


Probability\text{ that it is a face card = }(12)/(52)=\text{ }(3)/(13)

3)

The probability that it is a red or a face card

= probability that it is a red or a face card - probability that it is a red or a face card


\begin{gathered} =\text{ }(1)/(2)\text{ + }(3)/(13)\text{ - }(6)/(52) \\ =\text{ }(1)/(2)+\text{ }(3)/(13)\text{ -}(3)/(26) \\ =\text{ }\frac{13\text{ + 6-3}}{26} \\ =\text{ }(16)/(26) \\ =\text{ }(8)/(13) \end{gathered}
