Answer :

2/221 is the probability that a 2-card hand has two queens, two kings, or one of each.

What is probability?

  • Probability is a branch of mathematics that deals with numerical representations of the likelihood of an event occurring or the probability that a statement is true.
  • Probability varies between zero and 1, wherein zero approaches are not possible and 1 approach is certain.

Now, calculate the probability as follows:

  • There are 4 kings and 4 queens in a deck of cards.

Then, it can be either KK or QQ.

  • Select 2 kings from 4 king cards that can be done in 4c₂=6 ways.
  • Select 2 queens from 4 queen cards that can be done in c₂ = 6 ways.
  • Total ways = 52c₂ = 1326

So required probability = 2king or 2 queen

  • = 6/1326 + 6/1326
  • = 12/1326
  • = 2/221

Therefore, the probability that a 2-card hand (drawn from a standard deck of 52) has two queens, two kings, or one of each is 2/221.
