Determine t

Given that we need to draw 5 cards from a deck of 52 cards.

We need to find the no. of ways that at least one of the 5 cards has to be a king.

We know that there are 4 kings present in a deck.

Let us assume the no. of ways of drawing cards be N.

⇒ N = (Total no. of ways of drawing 5 cards out of 52 cards) – (No. of ways of drawing 5 cards without a king from remaining 48 cards)

⇒ N = (⁵²C₅) – (⁴⁸C₅)

We know that ,

And also n! = (n)(n – 1)......2.1

⇒

⇒

⇒ N = 2598960 – 1712304

⇒ N = 886656

∴ The no. of ways of drawing 5 cards with at least 1 king is 886656.
