Text Solution

Verified by Experts

The correct Answer is:
N/a
Let `S` be the sample space.
`:. n(S)=52`
Let `E=` event of drawing a card of heart
`F=` event of drawing a card of king.
`n(E)=13`
and `n(F)=4`
Now `EnnF=` event of drawing a card which is a king as well as a card of heart.
`implies n(EnnF)=1`
`P(EuuF)=P(E)+P(F)-P(EnnF)`
`=13/52+4/52-1/82`
`=16/52=4/13`
