Given P(A) = 0.44, P(B) 0.6 and P(An B) = 0.394, find the value of
geniusboy [140]

Given:

P(A)=0.44,P(B)=0.6,P(A\cap B)=0.394.

To find:

The value of P(A\cup B), rounding to the nearest thousandth.

Solution:

We know that,

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

On substituting P(A)=0.44,P(B)=0.6,P(A\cap B)=0.394, we get

P(A\cup B)=0.44+0.6-0.394

P(A\cup B)=0.646

Therefore, the value of P(A\cup B) is 0.646.

Is this answer correct?
hodyreva [135]

Answer:

No

Step-by-step explanation:

How to solve :

(a-4)/(a^2+8a+12)*(a^2-2a-48)/(a^2+4a-32)

Factor:

a^2+8a+12 = (a+6)(a+2)

a^2-2a-48 = (a-8)(a+6)

a^2+4a-32 = (a+8)(a-4)

simplify a+6, and a-4

you are left with (a-8)/(a+2)(a+8) = (a-8)/(a^2+10x+16)

Helpp?<br> Simplify (secx/cosx) - (tanx/cotx)
Elenna [48]
Secx = 1/cosx
cot x = 1/tanx
1 + tan^2(x) = sec^2(x)
minus tan^2(x) on both sides,
1 = sec^2(x) - tan^2(x)

sec(x)/cos(x) - tan(x)/cot(x)
=1/cos^2(x) - tan^2(x)
= sec^2(x) - tan^2(x)
= 1
