If P(A)=.55, P(B)=.32 And P(AuB)=.70,

son4ous [18]

Answer:

A. 0.5313

B. 0.15

Step-by-step explanation:

Given:

$P(A)=0.55\\ \\P(B)=0.32\\ \\P(A\cup B)=0.70$

First , use formula

$P(A\cup B)=P(A)+P(B)-P(A\cap B)$

to find $P(A\cap B):$

$0.70=0.55+0.32-P(A\cap B)\\ \\P(A\cap B)=0.55+0.32-0.70=0.87-0.70=0.17$

A. Use formula

$P(A|B)=\dfrac{P(A\cap B)}{P(B)}\\ \\P(A|B)=\dfrac{0.17}{0.32}=\dfrac{17}{32}=0.53125\approx 0.5313$

B. Use formula

$P(A'|B)=P(B)-P(A\cap B)=0.32-0.17=0.15$

Find the solution of this system of equations x-8y=21 and 3x--8y=15

devlian [24]

If you would like to find the solution of the system of equations, you can do this using the following steps:

x - 8y = 21 /*(-3)
3x - 8y = 15
______________
-3x + 24y = -63
<span>3x - 8y = 15
</span>______________
-3x + 24y + 3x - 8y = -63 + 15
16y = -48 /16
y = -48/16
y = -3

<span>x - 8y = 21
</span>x = 21 + 8y
x = 21 + 8 * (-3)
x = 21 - 24
x = -3

(x, y) = (-3, -3)

The correct result would be (-3, -3).
