Question

What is number of ways of selecting 4 cards out of a pack of 52 cards which include exactly one red Queen?​

Answer 1

The probability will be 7.692%.

Step-by-step explanation:

Since we know that there are total four queens in a pack of 52 cards.

• Therefore, The number of ways to draw one card =$^5^2C_1 = \dfrac{52!}{1!(52-1)!}$

• Similarly, the number of ways to draw 1 queen from 4 queens =$^4C_1 = 4$

• Thus, probability = $\dfrac{The\ number \ of \ ways \ to \ draw \ one \ queen \ from \ 4 \ queens}{The \ number \ of \ ways \ to \ draw \ one \ card}$

  $= \dfrac{4}{52}$ = $\dfrac{1}{13}$ = 0.07692                          

  Thus, the probability to draw one queen will be 7.692%.
