Answer 1

$Out \: of \: 52 \: cards \: one \: card \:can \: be$

$drawn\: in \: 52 \: ways .$

$So, total \: number \:of \: elementary \:events$

$= 52$

$a) There \: are \:26 \: red \:cards \: , including$

$4 \: spades, \: in \:a \: pack \:of \: 52 \: playing$

$cards .$

$Also , there \: are \: 2\: black \: spades$

$\therefore Favourable \: number \: of$

$elementary \: events = 28$

$\red{ Required \:: probability = \frac{28}{52}}$

$= \frac{ 7}{13}$

$b) There \: are \: 4 \: spades \: and \: 4 \:kings$

$in \: a \: pack .$

$\therefore Favourable \: number \: of$

$elementary \: events = 8$

$\red{ Required \:: probability = \frac{8}{52}}$

$= \frac{ 2}{13}$
