Explanation / Answer

Please note nCx = n! / [(n-x)!*x!]

A deck of cards has 13 of each of clubs, spades, diamonds and hearts = 52 cards.

The probability of an event P = Favourable outcomes/Total number of outcomes

Favourable outcome = P(Getting 13 clubs out of the 13 clubs) = 13C13 = 1 way

Total outcomes = Being dealt 13 cards from the 52 avalable cards = 52C13 = 6.35014 * 1011.

Therefore the required probability = 1/6.35014 * 1011 = 1.57477 * 10-12 or 1.5748 * 10-12.
