Answer:

The probability will be "0.8462". The more clarification is provided follows.

Step-by-step explanation:

K = King

Q = Queen

As we know, there are four Kings and four Queens in a pack of 52 cards.

∴ 4+4=8 (King and Queen)

So that the probability will be:

⇒  P((K\cup Q)^8)=1-P(K\cup Q)

⇒                       =1-\frac{8}{52}

⇒                       =0.8462

So that the above will be the right answer.
