Answer:
Let S be the sample space.
There are 52 playing cards in a pack
∴ n(S)=52
Let A be the event that the card drawn is a king
Total king in pack =4
∴ n(A)=4
∴ P(A)=
n(S)
n(A)
=
52
4
=
13
1
Let B be the event that the card drawn is a face card
Total face card in a pack =12
∴ n(B)=12
∴ P(B)=
n(S)
n(B)
=
52
12
=
13
