Bill Gates wrote a computer program that generates three random numbers

Allushta [10]

Answer:

1/1000

Step-by-step explanation:

The probability of two independent events A, B (independent = events that do not depend on each other) is given by the product of the individual probabilities of A and B:

$p(AB)=p(A)\cdot p(B)$ (1)

In this problem, the single event is "getting a 3" when extracting a random number between 1 and 10.

The total number of possible outcomes is

n = 10

While the number of succesfull outcomes (getting a 3) is only one:

$s=1$

So, the probability of drawing a 3 in 1 draw is

$p(3)=\frac{s}{n}=\frac{1}{10}$

Then, we want to find the probability of getting three "3" in 3 consecutive generations. These events are independent events, so we can use rule (1) to find the total probability, and we get:

$p(333)=p(3)p(3)p(3)=(\frac{1}{10})(\frac{1}{10})(\frac{1}{10})=\frac{1}{1000}$

andrew-mc [135]

Answer: 1404 cubic feet.

Step-by-step explanation:

Formula :

Volume of a rectangular prism is given by :

Volume= Area of the base x Height.

Given : Talishas bedroom is a rectangular prism.

The area of the floor = 156 square feet

The height of the floor = 9 feet

Then , the volume of Talishas bedroom = Area of floor x Height

= 156 × 9=1404 cubic feet.

Hence, the volume of Talishas bedroom= 1404 cubic feet.

Nora and her children went into a grocery store and she bought $11.95 worth of apples and bananas. Each apple cost $1.25 and eac

SIZIF [17.4K]

Answer: apples = 7 and bananas = 8

Step-by-step explanation:

Let x represent the number of apples and y represent the number of banana,

and it was said that the total apples and bananas altogether is 15 , that is

x + y = 15 ................. equation 1

Also,

1.25x + 0.40y = 11.95 ............. equation 2

Solving the two equations simultaneously ,

From the first equation, x = 15 - y ........... equation 3

substitute equation 3 into equation 2, we have

1.25(15 - y) + 0.40y = 11.95

18.75 - 1.25y + 0.40y = 11.95

18.75 - 0.85y = 11.95

18.75 - 11.95 = 0.85y

6.8 = 0.85y

therefore y = 6.8/0.85

= 8

substitute y = 8 , into equation 3

x = 15 - 8

x = 7

Therefore , she bought 7 apples and 8 banana

Stan savings account has a balance of $4706. After 4 years what will the amount of interest be at 4% compounded quarterly?

TiliK225 [7]

Answer:

Final amount after 4 years will be $5518.

Step-by-step explanation:

From the given question Principal amount in the account of Stan = $4706

and we have to calculate amount after 4 years with 4% interest compounded quarterly.

Formula will be final amount $A=A'(1+\frac{r}{n})^{nt}$

Here A' = $4706

t = 4 years

n = number of times compounded = quarterly that will be 4

r = .04

$A=4706(1+\frac{.04}{4})^{4\times 4}=4706(1+.01)^{16}$

$A=4706(1.01)^{16}=4706\times 1.17=$5518$

So the final amount after four years will be $5518.
