Answer:
a)p(s)=52
total face cards= 12
p(e)=12
p( of a face card will come) =p(e)/p(s)
=12/52
=3/13
b) no: of black queen =2
no: of red king =2
p(sample space)=52
p( number of events)=2+2=4
p( of black queen and red king)=4/52=1/13
c) no: of red king=3
p(sample space)=52
p( number of events)=2
p( red king)=2/52
=1/26
d) no: of jack of heart card = 1
p(sample space)=52
p( number of events)=1
p( a jack of heart )=1/52
e) no: of spades =13
p(sample space)=52
p( number of events)=13
p( spades)=13/52
=1/4
