Answer:

With replacement

$probability \ of \ spade = \frac{13}{52} = \frac{1}{4} \\\\ probability \ of red\ card = \frac{26}{52} =\frac{1}{2}$

$probability \ of \ spade \ then \ red\ card\ without\ replacement =$ $\frac{1}{4} \times \frac{1}{2} = \frac{1}{8}$

Without replacement

$probability \ of\ spade = \frac{13}{52} = \frac{1}{4} \\\\probability \ of \ spade\ again =\frac{12}{51} = \frac{4}{17}$

$probability \ of \ spade \ then \ red\ card\ without\ replacement = \frac{1}{4} \times\frac{4}{17} =\frac{1}{17}$
