Step-by-step explanation:
Given that Poker is a card played with a standard 52 card playing deck. We draw one card at a time without replacement from the top of a shuffled standard poker deck and stop when we draw an ace.
There are 4 aces and 48 non aces.
For randomly drawing card for first card we have probability for drawing ace = 4/52 and non ace = 48/52
X = no of cards we have drawn
If X is the total no of cards drawn, then the event should have been
first x-1 cards non aces, and the last card ace.
Hence P(X)
= Drawing x-1 cards from 48 non aces * drawing one card from remaining 52-(x-1) cards
= , x=1,2,.....49
