Consider the following system.

amm1812

Answer:

x = 1 y = 3

Step-by-step explanation:

4x - 1 = -3x + 6 Substitute the first equation for y in the second equation

+3x + 3x Add 3x to both sides

7x - 1 = 6

+ 1 +1 Add 1 to both sides

7x = 7 Divide both sides by 7

x = 1

Now plug this into the first equation

y = 4(1) - 1 Multiply

y = 4 - 1 Subtract

y = 3

A deck of ordinary cards is shuffled and 13 cards are dealt. What is the probability that the last card dealt is an ace?

alexandr1967 [171]

Answer:

The probability that the last card dealt is an ace is $\frac{1}{13}$ .

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 $4\times 51!$ .

The probability that the last card dealt is an ace is

$P=\frac{4\times 51!}{52!}$

$P=\frac{4\times 51!}{52\times 51!}$

$P=\frac{4}{52}$

$P=\frac{1}{13}$

Therefore, the probability that the last card dealt is an ace is $\frac{1}{13}$ .
