A right circular hollow cylinder is a 3D region enclosed by two right circular cylinders having the same axis and two parallel annular bases perpendicular to the cylinders' common axis which will be formed when you rotate the given by 360 degrees.
Answer:
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
