2. in a colledge there 20 students enrolled in commerce
only 90 students erolled in
mathematics only, 30 students enrolled
in both math & commerce and 60
enrolled for others. Find
The total number of stydents in a
colledge

there are 200 students

Step-by-step explanation:

let no if students enrolled in commerce be nA) and mathematics be n(B)

n only(A)=20

n only(B)=90

n (A intersection B)=30

n(AUB)=60

now

n(U)=20+90+30+60

n(U)=200

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
