Among 500 freshmen pursuing a business degree at a university, 311 are enrolled in an economics course, 243 are enrolled in a ma

Allushta [10]

Solution :

Let A = Economics, B = Mathematics

n(A) = 311, n(B) = 243, $n(A \cap B) = 135$

a). So, $n(A \cup B) = n(A) +n(B) - n(A \cap B)$

= 311 + 243 - 135

= 419

b). n(A only) = 311 - 135

= 176

n(B only) = 243 - 135

= 108

Exactly one of these two courses

$=\frac{176+108}{500}$

= 0.568

c). Neither economics nor mathematics

$=\frac{500-419}{500}$

$=\frac{81}{500}$

= 0.162

Lannie ordered 12 copies of the same book for his book club members. The book cost $19 each, and the order has a $15 shipping ch

SashulF [63]

Hey there!

First, we need to find how much Lannie paid for all 12 copies. To do this, all we have to do is multiply the unit price ($19) by how many copies he bought (12)

$19 x 12 = $228

So, he spent $228 on the books, but we also need at add the shipping charge:

$228 + $15 = $243

Therefore, the total cost of Lannie’s order is $243

Hope this helps you!

God bless ❤️

Brainliest would be appreciated
