Answer 2

$\bold{\boxed{\boxed{\huge{\underline{\underline{\red{\mathfrak{answer}}}}}}}}$

total no. of card=52

i)no. of black king=2

so, probability=

$\frac{2}{52}or \frac{1}{13}$

ii)no of black cards=26 and 2 kings

so, favorable outcome=28

probability=

$\frac{28}{52} or \: \frac{7}{13}$

iii) probability=

$\frac{2}{52} or \: \frac{1}{13}$

iv) probability=

$\frac{12}{52} or \: \frac{3}{13}$

v) no. of heart=13 or king=3(except heart's king)

favorable outcome=52-16=36

probability=

$\frac{36}{52} or \: \frac{9}{13}$

vi)no of spade=13 and ace=3(except spade's ace)

favorable outcome=16

probability=

$\frac{16}{52} or \: \frac{4}{13}$

vii)no of ace=4 and no of king=4

favorable outcome=52-8=44

probability=

$\frac{44}{52} or \: \frac{11}{13}$

viii) no. of red cards=26 and no. of queen=2(except red card queens)

favorable outcome=28

probability=

$\frac{28}{52} or \: \frac{14}{13}$
