The probability of **no** king is (12/13)(47/51)(23/25). The probability of "at least one king" is 1 minus that.

There are 52 cards in a deck and 52- 8= 44 are neither king nor queen. The probability the first card drawn is neither a king nor a queen is 44/52= 11/13. There are then 51 cards left, 43 neither king nor queen. The probability the second card is neither a king nor a queen is 43/51. There are then 50 cards left, 42 neither king nor queen. The probability the last card is neither a king nor a queen is 42/50= 21/25. The probability there is **no** king nor queen is (11/13)(43/51)(21/25). The probability there **is** at least one king or one queen is 1 minus that.
