Use the equation P(A or B)= P(B)-P(A and B) to find the missing value below.

Anvisha [2.4K]

Answer:

$P(B) = \frac{7}{8}$

Step-by-step explanation:

Given

P(A or B)= P(B)-P(A and B)

P(A)=1/3

P(A and B)=1/8

P(A or B)= 3/4

Required

Find P(B)

To find P(B), all we need to do is to substitute values of P(A or B) and P(A and B) in the given equation.

This goes thus;

P(A or B) = P(B) - P(A and B) becomes

$\frac{3}{4} = P(B) - \frac{1}{8}$

Make P(B) the subject of formula

$P(B) = \frac{3}{4} + \frac{1}{8}$

Take L.C.M

$P(B) = \frac{6 + 1}{8}$

Add fractions

$P(B) = \frac{7}{8}$

From the workings above, the value of P(B) using the given equation is $\frac{7}{8}$

Three girls bought a pizza for lunch. One girl ate 1/3 of the pizza another girl ate 1/4 of the pizza and the third ate the rest

Bad White [126]

One ate 1/3, Another ate = 1/4.

Total ate = 1/3 + 1/4 = (4 + 3) / 12 = 7/12

Fraction the third girl got = (The whole =1) minus 7/12

= 1 - 7/12 = (12 - 7) / 12 = 5/12

The third girl ate 5/12 of the pizza.

I WILL MARK BRAINLIEST! Solve for X

NARA [144]

Answer:

Step-by-step explanation:

You are to assume in both problems that the two triangles are similar. That is a very dangerous assumption -- especially in later math classes. But in this case, there is no other way to do the problem. The two sets of triangles look like they are proportional. So set up two ratios that are = to each other

On the left

long side small triange / long side large triangle = base small triangle / base large triangle

On the right

hypotenuse/longest leg = hypotenuse / longest leg.

Problem A

Set up the similar Proportion

5/40 = x/20 Cross Multiply

40x = 20*5

40x = 100 Divide by 40

x = 100/40

x = 2.5

Problem B

Again set up the similar triangle proportion

15/10 = x/2 Multiply by 2

15*2/10 = x

3 = x

Eighty percent of one store’s customers paid with credit cards. Forty customers came in that day. How many customers paid for th

Yuri [45]

Answer:

Step-by-step explanation:

40 = 100%

how many are 80% ?

well, 80% = 80× 1%

1% = 100% / 100

so, in our case

80% = 80×40/100 = 8×4 = 32

as a shortcut you consider a percentage x as a ratio factor of x/100 you multiply the 100% number with.

in our case

80% = 40 × 80/100 = 32
