Answer 2

Answer:

(a) Total cards=52

Number of black king cards=2

Number of black queen cards=2

Sum of black king cards and black queen cards=2+2=4

Probability of getting black king and black queen card = Number of favourable cases/Total outcome

=4/52

=1/13

(b) Total cards=52

Number of ten red cards=2

Number of red jack cards=2

Sum of ten red cards and red jack cards=2+2=4

Probability of getting ten red cards and red jack cards= Number of favourable cases/Total outcomes

=4/52

=1/13

(c) Total cards=52

Number of black face cards=6

Probability of getting black face cards=Number

of favourable cases/Total outcomes

= 6/52
