6. If n (E) = 40, n (A) = 22, n (ANB) = 8 and n ((AUB)') = 6, determine n(B)

Dimas [21]

Answer:

Step-by-step explanation:

First n(AUB)=n(E) - n((AUB)')

So n(AUB) = 40 - 6 = 34

Now all u hv to do is use the formulae,

n(AUB) = n(A) + n(B) - n(ANB)

So when u substitute above values,

34=22 + n(B) - 8

So,

n(B) = 4

What is 5/16 written as a percent?

Rom4ik [11]

First, you divide the fraction, and then you multiply it by 100.
So you get:
$\frac{5}{16} * 100$
$0.3125 * 100$
$31.25$

So, 5/16 is 31.25%

Hope this Helps! :)
