Given: A deck of 52 cards.
By using the formula,
P (E) = favourable outcomes / total possible outcomes
We now have to find the probability that all the face cards of same suits are drawn.
Total possible outcomes are
n (S) = 52C4
Let E be the event that all the cards drawn are face cards of same suit.
n (E) = 4 × 4C4 = 4
P (E) = n (E) / n (S)
= 4 / 270725
