Let A be the event that there are at least two fives among the four rolls. Let B be the event that there is at most one five amo

True [87]

Answer:

P(A) = 31/1296

P(B) = 125/1296

Step-by-step explanation:

Here, we want to find P(A) and P(B)

Let’s start with A

In a roll of a die, the probability that there will be a 5 is 1/6

The probability of not having a 5 is therefore 1-1/6 = 5/6

So out of four rolls , we want to find the probability of having at least two fives

This means there could be 2, 3 or 4 fives;

For two fives;

We have 2 fives and two non-fives

= (1/6 * 1/6 * 5/6 * 5/6) = 25/1296

For 3 fives;

we have 3 fives and 1 non five

= 1/6 * 1/6 * 1/6 * 5/6 = 5/1296

For 4 fives;

= 1/6 * 1/6 * 1/6 * 1/6 = 1/1296

So the probability of at least two fives is;

1/1296 + 5/1296 + 25/1296 = 31/1296

Event B is the probability that there is at most one five among the four rolls

That means there are 3 non fives and 1 five

P(B) = 1/6 * 5/6 * 5/6 * 5/6 = 125/1296

Valentino needs 4 1/2 pounds of chicken for a recipe. He already has

makvit [3.9K]

Answer:

Valentino needs 1 $\frac{3}{4}$ more pounds of chicken for the recipe.

Step-by-step explanation:

You just need to know how to subtract fractions.

Valentino needs 4 and 1/2 pounds of chicken for a recipe, and he already has 2 and 3/4. We want to know how many more pounds of chicken we need, so you subtract.

4 1/2 - 2 3/4 = 4 2/4 - 2 3/4

= 1 3/4

Valentino needs 1 and 3/4 pounds of chicken still.

A room is 20 feet long, 12 feet wide, and 10 feet high. What is the maximum distance from one corner to another

exis [7]

Answer:

25.38

Step-by-step explanation:

Its a 3-D block, so you have to find the distance from on corner to the opposite corner of the roof, but first find the distance from corner to corner on the floor.

20^2+12^2=c^2

400+144=544=c^2

c= $\sqrt{544}$

then find corner of floor to opposite roof corner.

100+544=644=c^2

c= $\sqrt{644}$

so its about 25.38 feet

A credit card company uses your average daily balance to compute your finance charge. You charge $100 on May 2 and $200 on May 2

liraira [26]

Answer:

Step-by-step explanation:

On may 2, charge = $100

On may 20, charge = $200

To get the average daily balance, we will use the concept of calculating slope;

let d be day of the month and c be the amount charged

when d1 = 2, c1 = 100

when d2 = 20, c2 = 200

average daily balance = c2-c1/d2-d1

average daily balance = 200-100/20-2

average daily balance = 100/18

average daily balance ≈ 5.56

Hence your average daily balance is approximately $5.56
