Solution

Since the number of red queen cards =2
and number of black king cards =2

Probability that first card is red queen and other is black king
=2C152C1×2C151C1=1663

and probability that first card is black king and other is red queen
=2C152C1×2C151C1=1663

Now, required probability
p=1663+1663=2663
Hence, the value of 663p is 2.
