At Davis you can buy 12 pounds of M&M's for $12.24 or 8 pounds for $8.24 at Smith's. Which is the better buy

Law Incorporation [45]

Answer:

12 pounds

Explanation:

If you were to divide 12.24 from 12 you would get 1.02, which would be the cost of each pound.

Meanwhile, if you were to divide 8.24 from 8 you would get 1.03, which would be the cost of each pound.

So although its only a 1 cent difference and you are technically spending more by buying the 12 pounds, if it were to buy 8 pounds from the cost of each pound for the 12 pounds, you'd only be spending $8.16 vs $8.24.

Because you would multiply 1.02, which is the cost of each pound for 12, by 8 and you would get 8.16.

A deck of 52 cards is shuffled. The first five cards of the deck are red. What is the probability that the last card in the deck

saveliy_v [14]

Answer:

The answer is " $\frac{1}{47}$ ".

Step-by-step explanation:

Although the five first players are red, the very first five cards are not spaded as the spad is a black card.

Its chance of the final card mostly on deck being the ace of spades is therefore determined as:

$= \frac{1}{\text{Number of remaining cards with the initial 5 cards}} \\\\= \frac{1}{47}$

Thus, $\frac{1}{47}$ here is the necessary chance.
