Solution

Find possible & total outcomes

Since total number of cards=52

$∴$ Favorable event=4 kings+13 heart+26 red-13(heart & red)-2(king & red)-1(King & heart)+1(King,red & heart)=28

$∴$ Required probability= $\frac{f a v o u r a b l e o u t c o m e s}{T o t a l p o s s i b l e o u t c o m e s} = \frac{28}{52} = \frac{7}{13}$
