Use the identity P(A ∪ B) = P(A)+P(B)-P(A ∩ B)

P(A)=0.50
P(B)=0.60
P(A ∪ B) = 0.30
=>
P(A ∪ B) = P(A)+P(B)-P(A ∩ B)
=(0.50+0.60)-0.30
=0.80

Which property explains why these two expressions are equal?
ratelena [41]
Re-written, I believe the equation is:

(W+23)+5=W+(23+5)

With this, the parenthesis have nothing multiplying into it, so we can drop the parenthesis to get:

W+23+5=W+23+5
Which is the same thing.

So I'd assume it is the Associative property, because you are combining the like terms of 23 and 5.

Hope this helps!

Pls help it says what is volume and how is it measured pls help
solmaris [256]

Volume is the measure of how much space a 3d object takes up (like area for 2d objects). It is measured in cubic parts (5 cubic inches, 12 cubic centimeters). There are many volume formulas. The easiest and most common is of the volume of a rectangular prism, for which you do lenght * width * height..

I hope this answers your question!

Plz tell me where to mark and the answers....
damaskus [11]
Well x=1 always unless it tells you other wise so 1+0.5 would equal 1.5 and so after that you keep adding so 1.5 + 0.5 equal 2 so you keep taking the previous answer and adding 0.5 to it
