Answer:
The probability that the last card dealt is an ace is .
Step-by-step explanation:
Given : A deck of ordinary cards is shuffled and 13 cards are dealt.
To find : What is the probability that the last card dealt is an ace?
Solution :
There are total 52 cards.
The total arrangement of cards is 52!.
There is 4 ace cards in total.
Arrangement for containing ace as the 13th card is .
The probability that the last card dealt is an ace is
Therefore, the probability that the last card dealt is an ace is .
A+8/3 = 2/3
Or, (3a+8)/3 = 2/3 [taking LCM]
Or, 3a+8 = 2 [3 in both denominators are cancelled]
Or, 3a = 2-8
Or, a = -6/3
.•. a = -2,,
Equation Form:
w x 2 19
Divide both sides by 2:
w 9.5
So, w must be equal to or greater than 9.5 for this equation to work.
