Answer:
A
Step-by-step explanation:
First your going to distribute the 3
3(-3x+15)
-9x+45
27=6x-9x+15
27=-3x+15
Then you’ll minus 15 from 27
27-15=12
12=3x
X=4
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
