according to the general equation for conditional probability of p(an B) = 3/10 and P(B)= 3/5, what is P(A|B)

2 answers:

4 0

The required formula is:
$P(A | B)=\frac{P(A\cap B)}{P(B)}$
Therefore the probability of A given B is:
$P(A|B)=\frac{\frac{3}{10}}{\frac{3}{5}}=\frac{3\times5}{10\times3}=\frac{1}{2}$

The sum of two numbers is 27. One number is 3 more than the other. Write and solve a system of equations to find the two numbers

givi [52]

X + y = 27
x = y + 3

y + 3 + y = 27
2y + 3 = 27
2y = 27 - 3
2y = 24
y = 24/2
y = 12

x = y + 3
x = 12 + 3
x = 15

ur numbers are 12 and 15

x= -0.25 and 1.25

x = -0.5 and 1.5

x = 0 and 1

x = -0.375 and 1.625

Step-by-step explanation:

Given equation of the curve is

$y = 4x^2 -4x-1$

(i)

First equation $4x^2 -4x-1 =0$

Here y = 0

In x-axis the value of y = 0

The graph cuts the x-axis at(-0.25,0) and (1.25,0)

So, x= -0.25 and 1.25

(ii)

$4x^2 -4x-1 =2$

here y = 2

The line y= 2 cuts the curve at (-0.5,2) and (1.5,2)

So, x = -0.5 and 1.5

Given equation of the curve is

$y= 3x^2-3x -1$

(i)

$3x^2-3x +2 =2$

$\Leftrightarrow 3x^2-3x -1 = -1$

Here y = -1

The line y = -1 cuts the curve at (0,-1) and (1,-1)

So x = 0 and 1

(ii)

$3x^2-3x -1 =x+1$

Here y = x+1

The line y -x =1 cuts the curve at (-0.375,0.5) and (1.625,2).

So x = -0.375 and 1.625
